+/**
+ * Creates a function that builds a new array by calling `callback` on every
+ * element, equivalent to `Array.prototype.map`. Use it with {@link pipe}.
+ *
+ * The returned function is **lazy-capable**: inside a {@link pipe} it is fused
+ * with adjacent lazy functions and runs element-by-element, so a trailing
+ * `take` can terminate the walk early without mapping the rest of the input.
+ *
+ * @template T - The type of elements in the input array.
+ * @template U - The type of elements in the output array.
+ * @param callback - Called with `(value, index)` for each element; its return
+ *   value becomes the corresponding element of the output array.
+ * @returns A function that maps a `readonly T[]` to a new `U[]`.
+ *
+ * @example
+ * import { pipe, map } from 'es-toolkit/fp';
+ *
+ * pipe([1, 2, 3], map(x => x * 2)); // => [2, 4, 6]
+ *
+ * @example
+ * // The index is available as the second argument.
+ * pipe([10, 20, 30], map((value, index) => value + index)); // => [10, 21, 32]
