Edit Question
Title
Body
In Python, where [2] is a list, the following code gives this output: [2] * 5 # Outputs: [2,2,2,2,2] Does there exist an easy way to do this with an array in JavaScript? I wrote the following function to do it, but is there something shorter or better? var repeatelem = function(elem, n){ // returns an array with element elem repeated n times. var arr = []; for (var i = 0; i <= n; i++) { arr = arr.concat(elem); }; return arr; };
