JavaScript Internals — Part 3: Closures, Garbage Collection and Memory Leaks

1. 1Read about execution contexts to understand how JavaScript code is executed
2. 2Learn about variable lifetimes and reachability to grasp how memory is managed
3. 3Study closures to see how they impact memory usage
4. 4Understand how garbage collection works in JavaScript
5. 5Apply this knowledge to identify and fix memory leaks in your code

Software engineers and developers working with JavaScript and React Native can benefit from understanding these internals to optimize their code and prevent memory leaks, while team leads and tech managers can use this knowledge to guide their teams towards better coding practices

💡 Closures can cause memory leaks if not managed properly, so understanding how they work is crucial for efficient coding
