Javascript Repeat a String

This can be done using the .repeat() method:


"abc".repeat(3);

Output

"abcabcabc"

"abc".repeat(0);

Output

""

"abc".repeat(-1);

Output

Throws a RangeError

In the general case, this should be done using a correct polyfill for the ES6 String.prototype.repeat() method.
Otherwise, the idiom new Array(n + 1).join(myString) can repeat n times the string myString:


var myString = "abc";
var n = 3;
new Array(n + 1).join(myString);

Output

"abcabcabc"
