How to escape from memory leaks in JavaScript

JavaScript applications can suffer from memory leaks, leading to frequent crashes and poor performance due to misconceptions about automatic memory management by JavaScript engines. Memory leaks occur when the JavaScript engine cannot reclaim allocated memory, often caused by flaws in the program's logic. Understanding memory management, including allocation and garbage collection, is crucial to resolving these issues. JavaScript uses the stack for primitive types and the heap for reference types, with garbage collection employing algorithms like reference count and mark-and-sweep to manage memory. Common causes of memory leaks include undeclared global variables, closures, forgotten timers, and out-of-DOM references. Developers can identify and address memory leaks using Chrome DevTools by visualizing memory consumption and identifying detached DOM nodes. Preventing memory leaks is essential for improving application performance and can be achieved by understanding and managing unwanted references effectively.
