Function insert

Can insert an array or a single element. Negative indices count backwards from the end of the array.

Remarks

Non-integer or out of bounds indices return the array unchanged. If index equals the length of the array, then elems will be appended to the end.

Example

import * as A from "flurp/array";

const insertOne = A.insert(2, 10);
insertOne([0, 1, 2, 3, 4]);    // [0, 1, 10, 2, 3, 4]

const insertMulti = A.insert(2, [10, 11, 12]);
insertMulti([0, 1, 2, 3, 4]);   // [0, 1, 10, 11, 12, 2, 3, 4]
