JSON

Since JSON object is missed only in very old engines like IE7-, Core-JS does not provide a full JSON polyfill, however, fix already existing implementations by the current standard, for example, well-formed JSON.stringify. JSON also fixed in other modules - for example, Symbol polyfill fixes JSON.stringify for correct work with symbols.

Modules

• es.json.to-string-tag
• es.json.stringify

Types

interface JSON {
  stringify(
    value: any,
    replacer?:
      | Array<string | number>
      | ((key: string, value: any) => any)
      | null,
    space?: string | number
  ): string | void;
  [Symbol.toStringTag]: "JSON";
}
