JSON (JavaScript Object Notation) and JavaScript Objects are related but not the same. JSON is a text-based data format for exchanging data, while a JavaScript Object is an in-memory data structure used within JavaScript programs.
Key distinctions:
Nature: JSON is plain text, language-independent, and follows a strict syntax. JavaScript Object exists only during program execution in JavaScript.
Syntax Rules: JSON keys and string values must be in double quotes. JavaScript Objects allow unquoted keys and can use single or double quotes for strings. JSON supports only strings, numbers, booleans, null, arrays, and objects. JavaScript Objects support all JS data types, including undefined and functions.
Functionality: JSON cannot contain methods or executable code. JavaScript Objects can have methods and complex logic.
