<ul data-eligibleForWebStory="true">Memory in JavaScript involves stack and heap memory allocation.Primitive values are stored in the stack while objects are stored in the heap.Stack memory is fixed, while heap memory can grow in size.Changes to variables in the stack memory do not affect other variables.Variables pointing to objects in heap memory share references, leading to changes reflecting across variables.Shallow copy only copies references, not the actual object.Deep copy duplicates the entire object structure including nested objects.JSON.stringify() and JSON.parse() can be used for deep copying objects.Serialization and deserialization are crucial for working with APIs, network requests, and data storage.Understanding memory allocation in JavaScript is essential for effective programming.
