Why Do JavaScript Memory Leaks Slow Down My App? Have you ever wondered how memory management works in JavaScript and what causes applications to slow down or crash? In this detailed video, we’ll explain the common reasons behind JavaScript memory leaks and how they impact your web apps. We’ll start by discussing how JavaScript handles memory through a process called garbage collection and what happens when objects are unintentionally kept in memory. You’ll learn about typical scenarios that lead to memory leaks, such as global variables, lingering DOM references, and closures that hold onto data longer than necessary. We’ll also cover how persistent data stored in global objects or caches can contribute to increasing memory usage over time.

Additionally, we’ll explore practical tools like Chrome DevTools that help identify memory leaks by monitoring heap size and pinpointing objects that aren’t released. You’ll discover best practices for managing event listeners, timers, callbacks, and promises to prevent memory from being unnecessarily retained. We’ll share tips on how to efficiently clear unused data and manage references, including the use of weak references and data structures like WeakMap. Understanding how to monitor and control memory usage is essential for maintaining a fast, responsive, and stable web application. Whether you’re a developer or just interested in how JavaScript works under the hood, this video will provide valuable guidance to keep your apps running smoothly.
