How to parse JSON string in Typescript

Question

Is there a way to parse strings as JSON in Typescript.
Example: In JS, we can use JSON.parse(). Is there a similar function in Typescript?

I have a JSON object string as follows:

{"name": "Bob", "error": false}

Answer 1

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);
