JavaScript the Hard Parts: Types, Operators & Metaprogramming

Ready to finally crack the code behind JavaScript’s quirks?

In this hands-on workshop, led by Codesmith co-founder and CAO Will Sentence, you’ll build a clear mental model of JavaScript’s type system and coercion mechanics so you can confidently predict operator results, interface cleanly with browser APIs and even take control under the hood with metaprogramming.
Guided by Will, you’ll trace values through the stack and heap, explore the difference between primitives and objects, and see exactly how the coercion pipeline works. Along the way, you’ll uncover the “why” behind those classic JavaScript gotchas - transforming frustrating quirks into powerful tools. Make sure to also RSVP for this event on our website to receive the Zoom link!

What you’ll learn:

• How primitives and objects are stored and passed through stack and heap
• Predicting operator outcomes (+, ==, ===, etc.) using the coercion pipeline
• Debugging unexpected coercions and tricky JavaScript behaviors
• Writing cleaner, safer code when working with browser APIs and type conversion
• Using well-known symbols to modify built-in features, without breaking backwards compatibility

By the end of this workshop, you’ll not only understand how JavaScript types, operators, and coercion really work - you’ll also know how to use them to your advantage, both in your day-to-day coding and in tough interview questions.
