<ul><li>JavaScript quietly allocates memory for new values like variables, objects, arrays, or functions when created.</li><li>Memory for small values is stored in variables, while larger structures are stored in heap memory.</li><li>Memory is reclaimed when a value is no longer reachable by any part of the running program.</li><li>JavaScript engines, like V8 and SpiderMonkey, use generational, incremental mark-and-sweep collectors.</li><li>Closures and DOM interactions are common causes of memory leaks in JavaScript.</li><li>Improperly cleared timers like setInterval and setTimeout can lead to memory leaks.</li><li>Detached DOM trees and undisposed event listeners can also cause memory leaks.</li><li>Proper memory management in JavaScript helps prevent slower performance, increased memory usage, and crashes.</li><li>Understanding reference creation and cleanup is crucial to avoiding memory leaks in JavaScript applications.</li><li>Regularly nullifying unnecessary references and cleaning up after closures and DOM manipulations can prevent memory leaks.</li></ul>
