Javascript JSON Tutorial

Javascript JSON

About

In this code snippet, we’ll learn about JSON serialization/deserialization in Javascript.

JSON or javascript object notation is a data format/structure for storing/transporting data. It’s supported by a wide variety of programming languages. It’s short, concise, easy to read/write and understand.

In Javascript, you can use the JSON.stringify() method to turn an object into a JSON string and JSON.parse() to turn a JSON string into an object.

Let’s see the example below.

Code:

//Just a demo object for serialization.
let languages = {
	title: "Programming Languages",
  languages: [
  	"Java",
    "Javascript",
    "C",
    "C++",
    "C#",
    "PHP",
    "Python"
  ]
}

//Serialize object to json.
let json = JSON.stringify(languages);
console.log(json);

//Deserialize json to object.
let languagesDeserialized = JSON.parse(json);
console.log(languagesDeserialized);
