Hi, I am a Javascript apprentice. Can you help me with my project?

- Sure! What do you need?

Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.

- Wait, why static? Why not dynamic?

I don’t know, I guess it’ll be easier.

- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.

You know that doesn’t make sense right?

- When you learn Javascript you’ll get it.

Okay, so I want to parse this date first to make the clock be universal for all the regions.

- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!

But it’s just two lines.

- Don’t reinvent the wheel!

Literally, Javascript has a built in library for t...

- One component per file!

I’m lost.

- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.

Doesn’t Javascript include that already?

- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.

What’s ECMAScript?

- Javascript

Why is it called ECMAScript then?

- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.

What does that have to do with my page?

- So you can install AngularJS.

What’s AngularJS?

- A Javascript framework that allows you to do complex stuff easily, such as two way data binding!

Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?

- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.

Then why make two way data binding in the first place?

- It’s backed up by Google. You just don’t get it do you?

I have installed AngularJS now, but it seems I have to redefine something called a... directive?

- AngularJS is old now, you should start using Angular, aka Angular 2.

But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?

- You mean 3.

2.

- 3.

4?

- 5.

6?

- Exactly.

Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.

- That’s good.

Really?

- Yes, except you didn’t concatenate your html into templates that can be under a super Javascript file which can, then, be concatenated along all your Javascript files and finally be minimized in order to reduce latency. And automate all that process using Gulp while testing every single unit of your code using Jasmine or protractor or just the Angular built in unit tester.

I did.

- But did you use TypeScript?

TL;DR: Stop using React for EVERYTHING. It's not the end-all solution to every application need.

My team is staffed about 50/50 with tenured devs, and junior devs who have never written a full application and don't understand the specific benefits of different libraries/framworks. As a result, most of these junior devs have jumped on the React train, and they're under the impression that React is the end-all answer to any possible application need. Doesn't matter what type of app is, what kind of data is going to be flowing through the app, data scale, etc. In their eyes, React is always the answer. Now, while I'm not a big fan of React myself, I will say that it does its job when its tasked with a data-heavy application that needs to be refreshed/re-rendered dynamically and frequently (like Facebook.) However, my main gripe is that some people insist on using it for EVERYTHING. They refuse to acknowledge that there can be better library/framework choices (Angular, Vue, or even straight jQuery,) and they refuse to learn any other frameworks. You can hit them with countless technical reasons as to why React isn't a good choice for a particular application, and they'll just spout off the same tidbits from the "ReactJS Makes My Nips Hard 101" handbook: "React is the future," "Component-based web architecture is the future," (I'm not arguing with that last one) "But...JSX bro.," "Facebook and Netflix use it, so that's how you know it's amazing." They'll use React for a simple app, and make it overly-complex, and take months to write something that should have taken them a week. For example, we have one dev who has never used any other frameworks/libraries apart from React, and he used React (via create-react-app) to write what is effectively a single form and a content widget inside of a bootstrap template. It took him 4 MONTHS to write this, and it still isn't fully functioning. The search functionality doesn't really work (in fact, it's just array filtering,) and wont return any results if you search for the first word in an entry. His repo is a mess, filled with a bunch of useless files that were bootstrap'd in via create-react-app. We've built apps like this in a week in the past using different libraries/frameworks, and he could have done the same if he didn't overly-complicate the project by insisting on using React. If your app is essentially a dynamic form, you don’t need a freaking virtual DOM.

This happens every time a big new framework hits the scene. New young developers get sucked into it, because it's the cool hip new framework (or in React's case, library.) and they use it for everything, even when it's not the best choice. It happened with Angular, Rails, and now it's happening with React.

React has its benefits, but please please please consider which library/framework is the best choice from a technical standpoint before immediately jumping on the React train because "Facebook uses it bro."

Why I hate typescript. Bored during quarantine so thought I rant a little more about this.
1. Compilation time, typescript increases project compilation time from 1 second to 3-4 seconds, which is basically triple or quadruple the time if you don't know math.
2. You write a minimum of 30% more code.
3. Many libraries are not written in TS by default, which means you end up having to manually install a fuckton of @types/(pckg name) manually which is incredibly shit.
4. Typescript is an absolute pain in the ass when using dynamic libraries. Plus when it works, it usually ends up finding maybe 1-2 errors in your code MAX, completely not worth it.
5.JSDoc is 100 times better. (Still don't use it though).
6. I actually enjoy loosely typed languages, having your compiler being smart enough to tell what the type of your input is is much better than it assuming you're a fucking retard so it forces you to manually type everything.

P.S if you hate loosely typed languages, kindly resort to Angular, C#, Java or whatever and leave JS alone, cunt.

The saddest and funniest side of our industry is (atleast in India): someone works hard and makes it to the best colleges, do great projects on AI, ML; get a good score on Leetcode, codechef; gets a job in FAANG-like companies...

Changes colors in CSS and texts in HTML.

And, why is there so much emphasis on Data Structures and Algorithms? I mean, a little bit is fine, but why get obsessed with it when you never write algorithms in production code?

Now, don't tell me that, we use libraries and we should know what we are doing, no, we don't use algorithms even in libraries.

Now, before you tell me that MySQL uses B-tree for maintaining indexes, you really don't need to solve tricky questions to be able to understand how a B-tree works.

It's just absurd.

I know how to little bit on how design scalable systems.
I know how to write good code that is both modular and extensible.
I know how to mentor interns and turn them into employees.
I know how to mentor junior engineers (freshers) and help them get started.
Heck I can even invert a binary tree.

But some FAANG company would reject me because I cannot solve a very tricky dynamic programming question.

When I first began with Python I really missed the static typed checking from Java, I barely know anything about a returned object from a method and have to read the API extensively for every new library.

After a while I finally understand why Python is so powerful, the combination of dynamic typed language and rich default methods make the language unbeatable for your productivity.

While Java's Object only has toString(), hashCode(), equals() or clone(), Python's basic Class has every fucking method for every scenario I could ever image. No wonder that libraries like numpy or pandas work so well and fluidly.

I keep forgetting what a massive pain in the ass it is to use dynamic libraries in anything other than C. I'm genuinely contemplating defining a serialization-based API and talking to plugins with a blob->blob function pair.

Hello tech community ,

Quick question. I have been learning web development casually over a couple of years. Now,I'm stepping up my game. Playing with big boy libraries like Vue and React. Diving into JavaScript and functional react.

I can make static websites. Even dynamic ones. I know how to deploy websites from my terminal and I have done an ftp once before ,which was weird. But it was a long time ago. OMG my question is how do you transfer over a project to a client? I made a cool site. Added some JavaScript. Maybe it's pulling in some data. Maybe it's static. What is the best course of action? I really want to start a web design/developer side hustle.

Thanks homies.

Linking problems are really fun... Like using gdb in the dark on incompatible exec or without debug symbols:
You change the order of the libraries or switch to dynamic linking for one of them and suddenly it works
