update
Object
since 4.6.0
Returns
Object `object`.
This method is like _.set
except that accepts updater
to produce the
value to set. Use _.updateWith
to customize path
creation. The updater
is invoked with one argument: (value).
Note: This method mutates object
.
Example of Lodash _.update
var object = { 'a': [{ 'b': { 'c': 3 } }] };
_.update(object, 'a[0].b.c', function(n) { return n * n; });
console.log(object.a[0].b.c);
// => 9
_.update(object, 'x[0].y.z', function(n) { return n ? n + 1 : 0; });
console.log(object.x[0].y.z);
// => 0
