I really like JS, but sometimes it's just incredibly stupid.
NaN stands for Not-A-Number
typeof NaN
> 'number'
why are you doing this to me8 -
Coworker: I give up! Please help me!
Me: What's up?
C: Take a look at this. I have this function here that gets the tab index and I'm passing it to the Tabs component over there. I'm logging the index and as you can see it's 3, but the Tabs component isn't working. However if I replace the function call with a 3 it works!
Coworker 2: While you were explaining all that, shellbug already thought about at least 3 reasons why that isn't working.
Me: **sighs** Of what type is the value that function is returning?
C: **stares at me for a few seconds** It's a number.
Me: Are you sure?
C: Well, it's returning 3.
Me: Please do a typeof.
It was string.8 -
Hey guys,
this rant will be long again. I'm sorry for any grammar errors or something like that, english isn't my native language. Furthermore I'm actually very sad and not in a good mood.
Why? What happened? Some of you may already know - I'm doing my apprenticeship / education in a smal company.
There I'm learning a lot, I'm developing awesome features directly for the clients, experience of which other in my age (I'm only 19 years old) can only dream.
Working in such a small company is very exhausting, but I love my job, I love programming. I turned my hobby into a profession and I'm very proud of it.
But then there are moments like the last time, when I had to present something for a client - the first presentation was good, the last was a disaster, nothing worked - but I learned from it.
But this time everything is worse than bad - I mean really, really worse than bad.
I've worked the whole week on a cool new feature - I've done everything that it works yesterday, that everything gets done before the deadline of yesterday.
To achieve this I've coded thursday till 10pm ! At home! Friday I tested the whole day everything to ensure that everything is working properly. I fixed several bugs and then at the end of the day everything seems to be working. Even my boss said that it looks good and he thinks that the rollout to all clients will become good and without any issues.
But unfortunately deceived.
Yesterday evening I wrote a long mail to my boss - with a "manual". He was very proud and said that he is confident that everything will work fine. He trusts me completly.
Then, this morning I received a mail from him - nothing works anymore - all clients have issues, everything stays blank - because I've forgotten to ensure that the new feature (a plugin) and its functionality is supported by the device (needs a installation).
First - I was very shoked - but in the same moment I thought - one moment - you've written an if statement, if the plugin is installed - so why the fuck should it broken everything?!
I looked instant to the code via git. This has to be a very bad joke from my boss I thought. But then I saw the fucking bug - I've written:
if(plugin) { // do shit }
but it has to be if(typeof plugin !== 'undefined')
I fucked up everything - due to this fucking mistake. This little piece of shit I've forgotten on one single line fucked up everything. I'm sorry for this mode of expression but I thought - no this can not be true - it must be a bad bad nightmare.
I've tested this so long, every scenario, everything. Worked till the night so it gets finished. No one, no one from my classmates would ever think of working so long. But I did it, because I love my job. I've implemented a check to ensure that the plugin is installed - but implemented it wrong - exactly this line which caused all the errors should prevent exactly this - what an irony of fate.
I've instantly called my boss and apologized for this mistake. The mistake can't be undone. My boss now has to go to all clients to fix it. This will be very expensive...
Oh my goodnes, I just cried.
I'm only working about half a year in this company - they trust me so much - but I'm not perfect - I make mistakes - like everyone else. This time my boss didn't looked over my code, didn't review it, because he trusted me completly - now this happens. I think this destroyed the trust :( I'm so sad.
He only said that we will talk on monday, how we can prevent such things in the feature..
Oh guys, I don't know - I've fucked up everything, we were so overhelmed that everything would work :(
Now I'm the looser who fucked up - because not testing enough - even when I tested it for days, even at home - worked at home - till the night - for free, for nothing - voluntary.
This is the thanks for that.
Thousand good things - but one mistake and you're the little asshole. You - a 19 year old guy, which works since 6 months in a company. A boss which trusts you and don't look over your code. One line which should prevent crashing, crashed everything.
I'm sorry that this rant is so long, I just need to talk to you guys because I'm so sad. Again. This has happend to frequently lately.16 -
I come from PHP and have been using jQuery as a crutch for years. I've dabbled in Node and obviously writing some vanilla JS is unavoidable, but now I'm starting to use ES6 with Babel and VueJS and the more I dig in, the more I hate javascript. Everything is an object (null, array), there seems to be a few gotchas with math (including the one pictured), nothing is strongly typed but types are very important (for instance, you can't loop an object and an array using the same code), and there are a lot of inconsistencies/functions missing. ucwords for instance. Why doesn't that exist? typeof only returns object, but Array.isArray and Object.isObject work fine. I'm going to give typescript a go soon and cross my fingers.

rant.GetType() == typeof(long)
I have voiced my unhappiness to the powers that be regarding having to sit in traffic for over an hour to get to work and an hour to get back home, in the hopes that some sort of resolution and compromise can be reached.
The response basically was, "We've never had anyone work from home before and this is very new to us, so we wouldn't know where to start and how to manage this."
Firstly, from what I've heard along the grapevine, someone has worked from home before. In fact, it was a developer... wouldn't you fucking know!
Secondly, you're the manager... FUCKING MANAGE! Yes this is perhaps "new" territory for the company, but it's certainly nothing new to the world. Or maybe I'm wrong?
How's about, rather than fucking "ummm-ing" and "ahhh-ing" about the working from home being a good idea or not, perhaps try saying, "You know what, let's try something for the next 3 months and see how it goes. We sit down and hash out when and how we are going to communicate regarding the work that needs to be done, and when you will need to come in for meetings and the like." If it doesn't work after 2 weeks, oh well... we tried. And if we're still going strong after month 4, I think we have a winner!
Perhaps it's a generational thing, seeing as management are Baby Boomers and I'm a Millennial? Then again, I could be wrong.
The point is that I see a potential solution to my problem that may actually work and benefit both parties, but they're either to fucking set in their old ass ways and stubborn to allow this. Or perhaps it's a thing of "if we do this for you, we have to do it for everyone", which they don't want to do.
But more importantly, they don't seem to get the whole notion of "a happy employee is a productive employee".

Actual production code:
function isEmpty(val) {
return typeof val === 'undefined'
|| val === undefined
|| !(val !== undefined);
}
I'm starting to think the "infinite monkeys" metaphor is not a metaphor...5 -
Just JavaScript things:
alert(typeof NaN); //alerts 'Number' alert(NaN === NaN); //evaluates false
What else would you expect?4 -
I think javascript is a great language, but it has some really ugly parts.
For some reason, it really annoys me that JS developers are ok with things like
if (typeof something === "undefined")
I mean, comparing strings like that!3 -
Why the heck does the C++ committee let Microsoft have so much influence over the language?
I mean they do not give a flying flamingo about language aesthetics!
No, no, we cannot have `typeof` in the C++ standard because Microsoft pulled `decltype` out of their nullptr.3 -
So.. I'm giving one of my employers webapps a visual refresher, new company branding and whatnot.
And then I stumbled onto a check that is not returning what anybody expects, and, well , I'm busy fixing things, yeah..? so I go digging.. 🤔
```
function isDefined(obj) {
return !(typeof obj === "undefined") || obj !== null;
}
```
Here's the fun part, these particular lines have been in the code base since before 2017, which is when my Git history starts, because that's when we migrated projects from Visual SourceSafe 6 over to Git. Yes, you read that right. They were still using VSS in 2017.
I've begged and pleaded with my last 3 bosses to let us thrown this piece of shit out our second story window and rewrite it properly. But no, we don't have time to rewrite, so we must fix what we have instead.
I lost 4 hours of my life earlier today, tracking down another error that has been silently swallowed by a handler with its "console.log" call commented out, only to find that it's always been like that, and it's an "expected error". 🤦
Please, just fucking kill me now... I just, I can't deal with this shit anymore.5 -
me: Imma start working on this project I have been putting off for a week
me after messing with the chrome console for 30 mins:

typeof rant === "Encouragement"
Never let your self down, try to be your own const in life that know his scope and traits well enough to construct a peacefull life without any uncatched exceptions. Also try to return something to the public, keeping your magic pointers to your private makes it hard to review your glorious source of thoughts. And if it is getting hard try to REST a bit and git some timeout.

the more i learn about web dev, the more i realise the reason for its mess up . There are 2 major problems in it : the people who create various important concepts and tools for web dev were 1) working on it without any collaboration and agreements on the philosophy and 2) were too stubborn on their ideology i guess.
There is no limitation to anything's functionalities, and the limits that are "defined" are badshit crazy. for eg:
====================================
HTML creator : "I am gonna make a language that would provide a skeleton to web page. it will just have the text and basic markers to let the scripting and styling engines/languages know which text is supposed to be rendered and how.
It won't provide any click or loading functionality.
someone: "So i guess opening a page or loading an image would be handled by JS or other programming language? also, bold , italic or division would be added via CSS?"
HTMLguy : Nah, my html engine would ALSO do that.
someone : what , why? won't that just be stupid and against your philosophy?
HTMLguy : WHAT? am too awesome, can't hear you
w3c , 50 yrs later : sorry can't change this, gotta support the 50 yrs of web dev and billion sites
=================================
CSS guy: I am gonna make the world's best beautifying stylesheet language to provide colors, styling, fonts and backgrounds to a page. every loadings and clicks would be handled somewhere else
Some1: cool, then clicks, hover and running of animation would be handled by JS only
CSSguy :Umm, i guess i could handle those.
Some1 wha-?
CSSguy : Thankyou Thankyou Thankyou for the nobel price!
====================================
JS guy : I am gonna make a god web programming language! It can do everything: add/remove html tags, add styling, control animations, control browser, handle clicks , perform operations, everything!
some1: cool! you must be making very large programming language with lots of modules.
JS guy: No! i am gonna keep it small. no built in classes and file imports! just use the functions directly. if someone wants the additional lib functionality, install them on your server
some1 : innovative! what's typeof NaN ?
JSguy :shut up.6 -
A TypeScript boolean/undefined Flag variable kept fucking up
true == true didnt hold true
checked the "typeof" in console and it's GOODDAMN STRING.
What's the point of TypeScript's "type safety" if a Boolean variable is holding a String type for whatever reason. URGHH I HATE JAVASCRIPT.23 -
hey node what type is this?
> typeof []
'object'
but then
> Object.defineProperties.call([])
Uncaught TypeError: Object.defineProperties called on non-object
so is [] an object or not?13 -
currentRant.GetType() != typeof(Rant)
I know a lot of us developer types have side projects to, well, keep us sane really!
But how many of your side projects actually make you a bit of extra cash on the side?4 -
try{
If(!res || typeof res == undefined || res == undefined){}
}catch(err){
// you just had to throw an error
} -
typeof NaN === 'number' ... why javascript?... why Not a Number type is number??... a couple of minutes later i've discovered isNaN function. 💪💪💪

Thinking to start smoking 🚬
Never tried it once in 26 years not even a sip even refused temptations from school friends
Now by starting a job, i have no security, ironically. I feel like i stepped at the leap of a bottomless pit and tomorrow i jump into it and fall... and fall....and fall..... No end.
I have no idea how to use ansible and rexify.org and thats what I'll need to use. I have no idea how to do devops with Azure, and thats what ill do. I only build devops with terraform on Aws.
The unknown of 9-5 is frightening me more than starting a business. Paradoxically, i think it would come as a relief to get fired within the first week from failing to complete literally everything
On top of that my blonde gf disappeared yesterday for 3-4 hours. No texts no phone calls. Called for 2 times no answer. Called 3rd time and got a voice message the phone was shut down. 3-4 hours later she said she was with mom at shopping and didnt have internet
I also caught her texting some random guy on instagram. They both have vanish mode enabled (texts delete themselves as soon as you leave the conversation). Confronted her today. She wont tell me the truth. Likes his pics on ig. Keeps lying. On a question "why do you have vanish mode enabled with him?" her answer is "well i guess married men always use vanish mode"
Im tired
Too much shit unraveling. The opening of 2024 already doesnt look good
Why do good people die in accidents or diseases but i dont and i live? Shits unfair. Why doesnt nature/God fucking kill me? I beg to die. I hope to die. I pray for something to kill me. It would come as such a relief.
This life is meaningless and empty to me. typeof(life) yields a void. I dont value it. Its shit. Whether succeed or fail its meaningless. Nihilism was right
I am literally a walking dead. Physically moving but spiritually dead. Mentally lost. I am the captain of a ship in the middle of the ocean who no longer knows where the ship is going
Why cant i just get cancer or something. Can cigarettes help me get it? Cause I'll start consuming that shit right away to speedrun that process
End it
