Arrow Function is not Replacement For function(){}

I have seen so many low effort articles that pretend to teach you about arrow functions and then they end up just show you how function was written before ES6 and then glorified new arrow function.

function(x) { return x }  // regarded as old 
x => x // hip new function in ES6

It is so frustrating, because you can get wrong impression that there is no difference in how they work.

I am making this post just so people are aware that there are more differences between these two functions and they should take deeper look into documentation.
