In this article we will show you the solution of create JSON object in JavaScript, let us understand JSON first. The JSON stands for JavaScript object notation.
It is a lightweight data-exchanging format. It is used basically with API. JSON is language-independent.
First, to understand JSON we have to understand some functions of JSON. In JSON, we often use two functions: -
1. JSON.stringify: json.stringify() creates a JSON string
const myJSON ={
"name" : "peter" ,
"age" : 23 ,
"city" : "paris"
};
const me = JSON.parse(myJSON) ;
console.log(me)
2. JSON.parse(): json.parse() converts a JSON string into an object.
const flower = {
"name" : "rose" ,
"season" : "winter" ,
"colour" : "red"
} ;
const myflower = JSON.stringify(flower) ;
console.log (flower) ;
