Write some code, that will flatten an array of arbitrarily nested arrays of integers into a flat array of integers. e.g. [[1,2,[3]],4] -> [1,2,3,4]. Your solution should be a link to a gist on gist.github.com with your implementation. When writing this code, you can use any language you're comfortable with. The code must be well tested and docum…

shallowify.js

const a = [ 23, 3, [ 5, 12, ], 11, ]
const b = [ [23, [233, 9, ], 11, ], 13, ]
const c = [ [ [ 222, 34, 55, 1, 7, ], 9, 1500, ], ]

const shallowify = arr => {
	let results = []
	arr.forEach(arrEl => {
		if (arrEl.constructor === Array) {
			results = [...results, ...shallowify(arrEl), ]
		} else {
			results = [...results, arrEl, ]
		}
	})
	return results
}

console.log(shallowify([a, b, c]))
