Access object child properties using a dot notation string [duplicate]

Answer 1

You can use lodash get() and set() methods.

Getting

var object = { 'a': [{ 'b': { 'c': 3 } }] };

_.get(object, 'a[0].b.c');
// → 3

Setting

var object = { 'a': [{ 'b': { 'c': 3 } }] };

_.set(object, 'a[0].b.c', 4);
console.log(object.a[0].b.c);
// → 4
