Could someone please explain how exactly '=>' works in JavaScript? I know it is shorthand for an anonymous function, but don't quite understand what it does technically
@keezee the MDN docs are pretty good on this! https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions
@keezee Yes. But it has some side-effects that you have to be aware of, like the `this` not being bound to the function. But yea in 99% it's a nicer/faster way of writing anonymous functions :p
@Eramdam is this new to JS? I feel it's becoming more and more frequently used in code I read
@keezee Yes. It was added in ES6/ES2015 so it's only supported in modern browsers (read: not IE at all) https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions#Browser_compatibility
@Eramdam Fucking. IE.
@keezee haha. To be fair IE11 is going to be unsupported very soon (or is it already? I don't remember) so you should be fine :p
@keezee If you've been missing out on JS for the past ~2years then you're in for a treat because there was A LOT going on :D
@keezee Oh boy! Well imho it's probably the best time to learn JS because much of the newest features make it feel like a decent language on many aspects :p
@keezee But yeah, as a rule of thumb. MDN is a goldmine and should be your #1 source for answers in most cases :p
@Eramdam Thanks so much! Where do you work at SF?
@keezee I'm a front-end engineer at https://frontapp.com
@Eramdam just gave Front a quick glance and read. Awesome write up from YC. That's huge! Grats homie 👊
@keezee Thanks man! I've been at this company for 2yrs (we were ~5 in an office in Paris at the time!) so, yeah, we're doing alright I guess :D
@Eramdam Fuck yah you are!! Killings da game

@Eramdam RTFM fucking MDN...haha I'm an idiot. So it seems like it really just saves you the hassle of physically writing 'function' and 'return' when dealing with anonymous functions. Correct? Just trying to talk it out to see if I grasp the basic concept of it
