How to parse JSON string in Typescript

Is there a way to parse strings as JSON in TypeScript?

For example in JavaScript, 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

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 also have a type for 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);
