JSON parse generic

βœ… Viability Checklist

My suggestion meets these guidelines:

  • [*] This wouldn't be a breaking change in existing TypeScript/JavaScript code
  • [*] This wouldn't change the runtime behavior of existing JavaScript code
  • [*] This could be implemented without emitting different JS based on the types of the expressions
  • [*] This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
  • [*] This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Adding generics to JSON.parse

πŸ“ƒ Motivating Example

interface MyInterface {
     test: string,
    example: number
}
const myArr = JSON.parse<MyInterface[]>(fetchResponseText);

Removing refrence

interface MyInterface {
     test: string,
    example: number
}
const myOtherArr = JSON.parse<MyInterface>(JSON.stringify(myArr));

πŸ’» Use Cases

Make it easier and more convinient to parse JSON.
