JSON

Ensemble Javascript provides two key methods to deal with the JSON objects.

Methods

parse()

The JSON.parse() static method parses a JSON string, constructing the JavaScript object described by the string.

Returns

Returns a Javascript object

Example -

const json = '{"result":true, "count":42}';
const obj = JSON.parse(json);
 
console.log(obj.count);
// Expected output: 42
 
console.log(obj.result);
// Expected output: true

stringify()

The JSON.stringify() static method converts a JavaScript value to a JSON string.

Types that are directly converted to json strings - string, number, array, object (map), boolean and date. Date objects are converted to string by calling the toISOString() method.

Returns

Returns a string representing the json object

Example -

console.log(JSON.stringify({ x: 5, y: 6 }));
// Expected output: '{"x":5,"y":6}'
