Create an array with same element repeated multiple times

Question

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; }; 

Answer 1

In ES6 using Array fill() method

console.log(   Array(5).fill(2) ) //=> [2, 2, 2, 2, 2]
