Lodash

updateWith

Object
since 4.6.0

Returns

Object `object`.

This method is like _.update except that it accepts customizer which is invoked to produce the objects of path. If customizer returns undefined path creation is handled by the method instead. The customizer is invoked with three arguments: (nsValue, key, nsObject).

Note: This method mutates object.

Example of Lodash _.updateWith

var object = {};

_.updateWith(object, '[0][1]', _.constant('a'), Object);
// => { '0': { '1': 'a' } }
