How Can I Repeat a String Multiple Times in JavaScript?

Repeating Strings in JavaScript

In Perl, repetition of strings is achieved using the syntax $a = "a" x 10. Is there an equivalent approach in JavaScript?

Solution:

JavaScript provides a built-in method called repeat(), which allows you to repeat a string a specified number of times. Simply use the syntax:

"a".repeat(10);

This will result in the string "aaaaaaaaaa".

Alternative Approach:

Prior to the introduction of repeat(), a common technique involved creating an array of the desired length and joining each element with the string to be repeated:

Array(11).join("a"); // "aaaaaaaaaa"

Benchmarking:

As pointed out in the answer, benchmarks suggest that using a for loop to append the character may be faster in Safari and Chrome, but not in Firefox. However, the repeat() method remains a simplified and concise approach.
