JavaScript: Understanding the Weird Parts
What you'll learn
- Grasp how JavaScript works and it's fundamental concepts
- Write solid, good JavaScript code
- Understand advanced concepts such as promises, async/await, closures, prototypal inheritance, IIFEs, classes, and much more.
- Drastically improve your ability to debug problems in JavaScript.
- Avoid common pitfalls and mistakes other JavaScript coders make
- Understand the source code of popular JavaScript frameworks
- Build your own JavaScript framework or library
Requirements
- Basic Javascript knowledge (variables, loops, and basic functions - that's all the course expects you to know!)
- A browser and text editor
Description
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.
Over the past decade, tens of thousands of developers count this course as the course they always go back to year after year -- the one that finally helped them grasp JavaScript and move to the next level in their web development career. Many students are now senior developers, business owners, managers, and educators!
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.
This is the original course that taught web developers the concepts of the execution context and execution stack, critical concepts to mentally grasp how JavaScript works and how you code in it.
This course will cover such advanced concepts as objects and object literals, function expressions, function objects, prototypical inheritance, functional programming, scope chains, block scoping, classes, immediately invoked function expressions (IIFEs), call, apply, bind, promises, async, await and more.
We'll take a deep dive into the source code of popular frameworks 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 React, Node.js, Next.js, Angular, Vue, MongoDB, and all other Javascript-based technologies!
Learn to love JavaScript, and code in it well.
Note: In this course you'll also get downloadable source code. You will often be provided with 'starter' code, giving you the base for you to start writing your code, and 'finished' code to compare your code to.
Who this course is for:
- 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

Born and raised in Cleveland Ohio, now married and living in upstate New York, Tony is primarily focused these days on trying to be a good husband. While inexperienced at that, he's quite experienced in all things web.
Tony has been programming since he was 12 years old, and got into web sites and web application development at 16. After graduating with a Computer Science degree from Case Western Reserve University, Tony continued with that interest as a software application developer and architect, database designer, and user interface designer.
His 25 years of experience has ranged across technologies such as modern semantic HTML, CSS, JavaScript, React, Angular, Vue, Node.js, SQL as well as user experience design, usability testing and more.
He believes strongly that deeply understanding any topic allows you to properly learn it and, even more importantly in a real-world environment, quickly overcome problems.
He also has a deep interest in human nature and behavior, and how that impacts human-computer interaction. This interest translated into extending his career into user experience design and usability research.
Another link in the chain is his 25 years of experience in public speaking and teaching, both in front of large groups and as a one-on-one private instructor.
Putting all these pieces together, he has spent his career listening to a client need, designing a database and software to meet that need, building it, testing it, teaching others how to use it, then improving user experience by watching people actually use it and adjusting accordingly.
Tony loves teaching every aspect of what he does, and even more loves teaching in a way that imparts understanding, as opposed to just examples intended to be parroted. He loves that moment when a student 'gets it', and that's what he wants for you when you take one of his courses.
He has found that those that learn purely by example, and not by understanding, end up much more limited than they need to be.
"Examples need to be built on top of context, and once you have context, you can not only copy the examples you find, but adjust and improve upon them."
He firmly believes that everyone has the ability to develop software, if they are just taught properly. Including you.
"It is my pleasure and privilege to teach you. I hope you'll come away knowing something you didn't before, understanding at a level deeper than before, and feeling positive that you can accomplish what you've set out to accomplish. Thank you!" - Tony Alicea
