@monstermann/fn/dist/array/replaceLastOr.d.ts

A utility library for TypeScript.

//#region src/array/replaceLastOr.d.ts
/**
 * `replaceLastOr(target, value, replacement, or)`
 *
 * Replaces the last occurrence of `value` with `replacement` in `target` array. If the value is not found, returns the fallback value `or`. If value and replacement are the same, returns the original array unchanged.
 *
 * ```ts
 * replaceLastOr([1, 2, 3, 2], 2, 5, []); // [1, 2, 3, 5]
 * replaceLastOr([1, 2, 3], 4, 5, []); // []
 * ```
 *
 * ```ts
 * pipe([1, 2, 3, 2], replaceLastOr(2, 5, [])); // [1, 2, 3, 5]
 * pipe([1, 2, 3], replaceLastOr(4, 5, [])); // []
 * ```
