Serialization is the process of converting a data structure or object into a format that can be stored or transmitted, usually into a string. In JavaScript, JSON (JavaScript Object Notation) is usually used for serialization.
Basic data types (such as strings, numbers, Boolean values, etc.) do not require serialization because they can be stored and transmitted directly. Serialization is usually used to convert complex data structures (such as objects, arrays, etc.) into strings for use during network transmission or persistent storage.
Serialization is very useful when it comes to complex data structures such as objects and arrays. Basic data types do not need to be serialized because they are born in a form that can be stored and transmitted.
Therefore, basic data types do not need to be serialized, but can be processed and transmitted directly. Serialization is more commonly used for conversion of complex data structures.
