function set(object, path, value) {
      return object == null ? object : baseSet(object, path, value);
    }
Sets the value at `path` of `object`. If a portion of `path` doesn't exist,
it's created. Arrays are created for missing index properties while objects
are created for all other missing properties. Use `_.setWith` to customize
`path` creation.

**Note:** This method mutates `object`.

console.log(object.a[0].b.c);

_.set(object, ['x', '0', 'y', 'z'], 5);
console.log(object.x[0].y.z);
// => 5
