How to use JSON.stringify() method In Typescript
Since TypeScript is a superset of JavaScript, it also provides the JSON.stringify() method to convert a JavaScript object into a JSON string. It is the easiest and most concise way to convert a TypeScript dictionary to a string.
Syntax
let dictString: string = JSON.stringify(dictionary);
Example: The below code uses JSON.stringify() method to convert the TypeScript dictionary to a string.
interface Dictionary {
[key: string]: string;
}
let dictionary: Dictionary = {
name: "w3wiki",
desc: "A computer science portal",
est: "2009",
};
let dictString: string =
JSON.stringify(dictionary);
console.log(dictString);
Output:
"{"name":"w3wiki","desc":"A computer science portal","est":"2009"}"
