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.

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.
