I would still love to have something like that in ES6 (loosely similar to
String.prototype.repeat). Once you have that, you can e.g. use
Array.prototype.map to do more things.
Two possibilities:
- Array.repeat(undefined, 3) -> [ undefined, undefined, undefined ]
- [ undefined ].repeat(3) -> [ undefined, undefined, undefined ]
The same array could be created like this, but that seems too much work for a
relatively common operation.
'x'.repeat(3).split('').map(=> undefined)
