/**
 * `mapMerge(target, map)`
 *
 * Merges `target` object with the result of calling `map` function on `target`, creating a new object with existing keys updated.
 *
 * ```ts
 * mapMerge({ a: 1, b: 2 }, (obj) => ({ a: obj.a * 2 })); // { a: 2, b: 2 }
 * ```
 *
 * ```ts
 * pipe(
 *     { a: 1, b: 2 },
 *     mapMerge((obj) => ({ a: obj.a * 2 })),
 * ); // { a: 2, b: 2 }
 * ```
