array-split

What does it do?

Splits an array into multiple arrays using a predicate function.
returns an object containing the results keyed based on the return value of the predicate function.

How do I use it?

Example: Separate odd and even numbers

``
const split = require('array-split');

const numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9];

const result = split(numbers, (num) => {
if (num % 2 === 0) return 'even';
return 'odd';
});
`

This will return...

`
{
even: [2, 4, 6, 8],
odd: [1, 3, 5, 7, 9]
}
`

Anything else?

The predicate function only supports returning types...
null, undefined, string or number

- If you return null or undefined the value is dropped from the result set.
- If you return a string or a number`, it is keyed in the results object (numbers are converted to strings)
