/**
|
|
* Creates a copy of the passed object by applying an `fn` function to the given `prop` property.
|
|
*
|
|
* The function will not be invoked, and the object will not change
|
|
* if its corresponding property does not exist in the object.
|
|
* All non-primitive properties are copied to the new object by reference.
|

* @func
|
|
* @memberOf R
|
|
* @category Object
|
|
* @sig Idx -> (v -> v) -> {k: v} -> {k: v}
|
|
* @param {String|Number} prop The property to be modified.
|
|
* @param {Function} fn The function to apply to the property.
|
|
* @param {Object} object The object to be transformed.
|
|
* @return {Object} The transformed object.
|
|
* @example
|
|
*
|
|
* const person = {name: 'James', age: 20, pets: ['dog', 'cat']};
|
|
* R.modify('age', R.add(1), person); //=> {name: 'James', age: 21, pets: ['dog', 'cat']}
|
|
* R.modify('pets', R.append('turtle'), person); //=> {name: 'James', age: 20, pets: ['dog', 'cat', 'turtle']}
