Description: Memory management in JavaScript refers to the process of allocating and freeing memory in applications written in this language. Since JavaScript is a high-level programming language, its memory management is primarily done automatically, meaning developers do not have to worry about manual memory allocation and deallocation. This process includes creating objects, allocating memory space for them, and subsequently freeing that space when it is no longer needed. Garbage collection is a key feature in JavaScript’s memory management, allowing the JavaScript engine to identify and remove objects that are no longer accessible, thus freeing up the memory they occupied. This helps prevent memory leaks, which can occur when objects are unnecessarily referenced, preventing the operating system from reclaiming that memory. Efficient memory management is crucial for application performance, especially in environments where large volumes of data are handled or complex operations are performed. In summary, memory management in JavaScript is a fundamental aspect that enables developers to create more efficient and sustainable applications without having to deal with the complexity of manual memory management.
