npm install array-append-until --save

You can also use Duo, Bower or download the files manually.

var appendUntil = require('array-append-until')
appendUntil('Z', (list) => list.length === 2)
//=> ['Z', 'Z']

var appendUntil = require('array-append-until')
appendUntil((list) => list.pop() + 5, (list) => list.length === 3, [0])
//=> [ 0, 5, 10 ]

(Array) New array with element (or value returned from applying list to element function) appended.
