Guys I need some advice. I have read some articles about sass and less. I now know sass is using Ruby and Less is using JS. Can somebody tells me the big differences of both and which is the better one to learn? (in your opinion) Thanks

For what?

@heyheni f.e. multistore webshop

Then learn Sass, because bootstrap is written in it and its more used than less.

For personal projects i would recomend stylus

@heyheni thanks. Stylus looks clean! Great advice

Doesn't matter. SASS have much more features. But I prefer LESS. Because less syntax is more friendly.

Personally prefer SASS. Not had a good time with LESS & found SASS easier to work with.

Don't forget to use gulp to compile!

Sass and Less both are good, in the long run it comes down to personal prefference.

Neither of them are really hard to learn, so I'd suggest giving both a try.

Bootstrap 3 is written in Less but the upcoming v4 will be in Sass.

My guess is a lot of projects will shift from Less to Sass once bs4 comes out of alpha.

I like my codebase to be uniform, so up to now I used less, that enabled me to set bootstrap variables directly in my project files, but i will shift to sass for bs4.

You can get run Sass with other languages. I use Sass with mom (JavaScript).

Sass/SCSS is used by a lot more people than any other CSS preprocessor so I would suggest that over Less.
