/**
|
|
* Creates a new object by recursively evolving a shallow copy of `object`,
|
|
* according to the `transformation` functions. All non-primitive properties
|
|
* are copied by reference.
|
|
*
|
|
* A `transformation` function will not be invoked if its corresponding key
|
|
* does not exist in the evolved object.

|

* @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.

|
|

|
|
* const tomato = {firstName: ' Tomato ', data: {elapsed: 100, remaining: 1400}, id:123};

|
* const transformations = {

|
|
* data: {elapsed: R.add(1), remaining: R.add(-1)}

* };
|
|
* R.evolve(transformations, tomato); //=> {firstName: 'Tomato', data: {elapsed: 101, remaining: 1399}, id:123}
