Through a dot-separated path (example: 'subObject.foo.bar') you can find an object inside another parent object.

/**
 *
 * @param object where you want to find the result object

 * @description Given a path divided by dots (example: 'foo.bar') you can find an object inside another parent object
 * @example
 * const path = 'foo.bar'
 * const obj = { foo: { bar: 'hello' } }
 * console.log( getObjectInObject( obj, path ) ) //output: 'hello'
