JavaScript: Understanding the Weird Parts
In this course you will gain a deep understanding of Javascript, learn how Javascript works under the hood, and how that knowledge helps you avoid common pitfalls and drastically improve your ability to debug problems. You will find clarity in the parts that others, even experienced coders, may find weird, odd, and at times incomprehensible. You'll learn the beauty and deceptive power of this language that is at the forefront of modern software development today.

Javascript is the language that modern developers need to know, and know well. Truly knowing Javascript will get you a job, and enable you to build quality web and server applications.
NOTE: This course includes information on ECMAScript 6 (ES6) the next version of Javascript!
This course will cover such advanced concepts as objects and object literals, function expressions, prototypical inheritance, functional programming, scope chains, function constructors (plus new ES6 features), immediately invoked function expressions (IIFEs), call, apply, bind, and more.
We'll take a deep dive into the source code of popular frameworks such as jQuery and Underscore to see how you can use your understanding of Javascript to learn (and borrow) from other's good code.
Finally, you'll learn the foundations of how to build your own Javascript framework or library.
What you'll learn in this course will make you a better Javascript developer, and improve your abilities in AngularJS, NodeJS, jQuery, React, Ember, MongoDB, and all other Javascript-based technologies!
Learn to love Javascript, and code in it well.
- Those with basic Javascript skills who wish to improve
- Experienced coders coming from other programming languages
- New and experienced Javascript coders who want to deepen their understanding of the language
- Anyone who has found concepts just as object prototypes, closures, and other advanced concepts difficult to learn
- Those who have suffered surprising errors while writing Javascript, and want to learn why and how to avoid them
- Those interested in building their own frameworks, or being better able to learn from the source code of other well-known frameworks and libraries
