Chunk converts arrays like
[1,2,3,4,5] into arrays of arrays like
[[1,2], [3,4], ].
You can install chunk using npm.
npm install chunk
To chunk an array into an array of smaller arrays, simply call chunk:
> var chunk = require('chunk') > chunk([1,2,3]) [ [ 1, 2 ], [ 3 ] ]
To chunk an array into an array of N-sized arrays, call chunk with N:
> chunk([1,2,3], 1) [ [ 1 ], [ 2 ], [ 3 ] ] > chunk([1,2,3], 3) [ [ 1, 2, 3 ] ]
The default chunk size is 2.
