# JavaScript string repeat

Did you know JavaScript comes with a handy `repeat()` function?

It allows us to repeat a string an x number of times.

This uses to be a tedious process making use of loops or while arrays.

Now we can simply call `repeat()` on a string.

## Making use of JavaScript string.repeat()

As mentioned you can call this function on a string and it will repeat it an x number of times.

This x is the one and only argument it takes.

```js
'two'.repeat(2);
// 'twotwo'
```

This makes it far clearer for the code to state a string is repeated two times.

Old-school you might have found yourself doing something like this.

```js
let output = '';
for (i = 0; i < 2; i++) {
  output += 'two';
}
```

As you can see a more tedious process. (There are some alternatives, but nothing as simple as calling `repeat()`).

## Browser support

The browser support for the string.repeat is pretty good, only IE can't deal with it.
