Answer

JSON is a text format for serializing structured data. • JSON supports objects, arrays, strings, numbers, booleans, and null. • It does not directly represent undefined, functions, symbols, BigInt, or cyclic references. • JSON.parse reads JSON text and JSON.stringify creates JSON text from supported values.

Example

Code

const text = '{"name":"Maya"}';
console.log(JSON.parse(text).name);

Output

Maya
