How does JavaScript handle memory

JavaScript manages memory automatically through a process known as garbage collection. The JavaScript engine allocates memory for objects and variables during execution, and when they are no longer in use, the garbage collector reclaims that memory, keeping the application efficient and preventing memory leaks.

To illustrate this, consider the following example:

// Example of memory management in JavaScript function createObject() { let obj = { name: "John", age: 30 }; return obj; } let person = createObject(); console.log(person); // Once 'person' is no longer used, // it becomes eligible for garbage collection. person = null; // Now the memory can be reclaimed
