JavaScript The Hard Parts, v3

Build a robust mental model of callbacks and higher order functions, closure, types & operators, asynchronous JavaScript and object-oriented JavaScript.
Key Takeaways
By participating along with us in the workshop, you'll learn
How higher order functions like map, reduce and every are really working so you can use and rebuild them effectively
How the asynchronous world of JavaScript works - in terms of the call stack, callback queue, event loop and threads
Object-oriented programming and the different Object-oriented patterns available to us in JavaScript through the prototype chain
One of the most misunderstood but most powerful features of JavaScript - closure - by understanding execution context, JS runtime and the variable environment
How to solve any JS quirk problem and write code that is both flexible and predictable by understanding types, operators, coercion and meta-programming
Is This Workshop for Me?
This workshop is for intermediate to advanced JavaScript developers who want to deepen their understanding of the language's core mechanisms and challenging concepts. It's particularly valuable for developers preparing for technical interviews or those who want to confidently tackle complex JavaScript problems and write more sophisticated, maintainable code.
Workshop Details
We begin with callbacks and higher order functions like map, reduce, and filter-powerful tools that keep code DRY but can be complex to navigate. Next, we tackle closure, JavaScript's most misunderstood yet powerful feature, using execution context and variable environment concepts to understand functions like once, memorize, and password-protected functions. We'll explore asynchronous JavaScript under-the-hood, examining the call stack, event loop, and task queue to help you navigate complex async problems with confidence.
Building on this foundation, we'll construct a mental model of JavaScript's types, operators, and coercion mechanics, making the language's "quirks" entirely predictable while giving you more flexibility with Symbols and meta-programming. Finally, we'll explore popular Object-oriented programming patterns in JavaScript, learning how the 'this' and 'new' keywords work under-the-hood with the prototype chain to complete your comprehensive understanding of JavaScript's core mechanisms.
Any Prerequisites?
Intermediate JavaScript developers who are comfortable with JavaScript syntax, DOM manipulation, and object-oriented topics
