setAt

function Array.setAt<T>(
    target: readonly T[],
    idx: number,
    value: NoInfer<T>,
): readonly T[]

Sets the value at the specified idx in target to value. Returns the original array if the index is out of bounds or the value is already the same.

Example

data-first

import { Array } from "@monstermann/array";

Array.setAt([1, 2, 3], 1, 9); // [1, 9, 3]
Array.setAt([1, 2, 3], -1, 9); // [1, 2, 9]
Array.setAt([1, 2, 3], 5, 9); // [1, 2, 3]

data-last

import { Array } from "@monstermann/array";

pipe([1, 2, 3], Array.setAt(1, 9)); // [1, 9, 3]
pipe([1, 2, 3], Array.setAt(-1, 9)); // [1, 2, 9]
pipe([1, 2, 3], Array.setAt(5, 9)); // [1, 2, 3]
