JSON.parse

Parses a JSON string and converts it into a JavaScript object.

Signature

function parse<T>(data: string): T

Description

The parse method converts a JSON string into a JavaScript object. You can optionally specify a generic type parameter to ensure type safety of the returned value.

Examples

Basic usage

const jsonString = '{"a":1,"b":2,"c":3, "d": [1, 2, 3]}';

const result = JSON.parse(jsonString);
print(result); // {a: 1, b: 2, c: 3, d: [1, 2, 3]}

Using type inference

const jsonString = '{"a":1,"b":2,"c":{"e": 1, "f": 2}, "d": [true, false]}';

interface CustomData {
  a: number;
  b: number;
  c: Map<string, number>;
  d: boolean[];
}

const typedResult = JSON.parse<CustomData>(jsonString);
// Returns properly typed object with enforced structure
