- * Creates a new object by recursively evolving a shallow copy of `object`,

- * are copied by reference.
- *
- * A `transformation` function will not be invoked if its corresponding key
- * does not exist in the evolved object.

- * @memberOf R
- * @since v0.9.0
- * @category Object
- * @sig {k: (v -> v)} -> {k: v} -> {k: v}
- * @param {Object} transformations The object specifying transformation functions to apply
- * to the object.
- * @param {Object} object The object to be transformed.
- * @return {Object} The transformed object.
- * @example
- *
- * const tomato = {firstName: ' Tomato ', data: {elapsed: 100, remaining: 1400}, id:123};
