       What's a readable #javascript golf for a numeric for loop one can use in a one-liner?Everything I come up with ends up being about as complicated as just writing out a C-style for loop like it's the year I was born

       @darkwiiplayer unsure if that satisfies readable, but something like[...Array($your_size).keys()]    .map(item => {        /*put your code in here*/        /* variable item contains the current iteration */    });

       @4censord @darkwiiplayer  This is considerably bigger than for(let item=0;item<$your_size;item++) /*put your code in here*/, thus doesn’t satisfy golf

       @4censord @darkwiiplayer  i would’ve at least done [...Array(num)].map((_,i) => /* ... */)

       @kimapr The fact that [...10] isn't a thing in JS borders on infuriating

       @darkwiiplayer  … no actually, it’s a good thing that they didn’t add this

       @kimapr @darkwiiplayer uhh  why ?  /genlike rust  has  this syntax for  range iterators

       @fiore @darkwiiplayer  Okay but in javascript this would mean, “a number is now iterable and explodes into an amount of dummy elements”I.e.  makes no senserust does not have this syntax for range iterators

       @fiore @darkwiiplayer  though i thinked about it for 3 seconds, and i realize that it’s pretty trivial to implement exactly this behavior in javascript without language changesNumber.prototype[Symbol.iterator] = function*(i){for(let i=0;i<this;i++)yield i}then typing [...10] would produce [0,1,2,3,4,5,6,7,8,9] …Or in a “foreach” loop:for (let i of 10)  console.log(i);A better, more useful idea would be something like this:Number.prototype.to = function*(j){for(let i=+this;i<j;i++)yield i};for (let i of (0).to(10))  console.log(i);to implement iterable ranges as can be found in rust
