Stringify JSON object in typescript

To stringify json object in typescript, use JSON.stringify() it will convert your json object to json string.

The JSON.stringify() method converts a JavaScript object or value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified.

interface domain {
    name: string,
    domain: string,
}

const arr: Array<domain> = [
        {
            name: "infinitbility",
            domain: "infinitbility.com"
        },
        {
            name: "aguidehub",
            domain: "aguidehub.com"
        }
    ];

// ✅ Convert array of object to string
const str: string = JSON.stringify(arr);
console.log(str); // 👉️ '[{"name":"infinitbility","domain":"infinitbility.com"},{"name":"aguidehub","domain":"aguidehub.com"}]'

Note: The toString() and join() method only work for array of string, number not object.

I hope it helps you, All the best 👍.
