This course is out of date and does not reflect Frontend Masters current standards. We now recommend you take the JavaScript: The Hard Parts course.
Gain an advanced understanding of difficult JavaScript concepts such as JavaScript closure, new keyword, “this”, prototypical inheritance, type comparators, coercion and delete. Learn what happens in memory with pointers when using assignments and "delete". Then learn what's under the hood of the popular jQuery library by building your own version of the library in vanilla JavaScript and the DOM API. Learn to build interactive components from scratch using pure DOM scripting and advanced JS concepts.
This course and others like it are available as part of our Frontend Masters video subscription.
