Update lib.es5.d.ts

[ahmedkamalio]

Update JSON.parse to accept optional type parameter and return this type "any by default".

Example:

let parsedObj = JSON.parse<TypeObj>("{ prop: 'val' }"); // parsedObj is TypeObj

is way better than

let parsedObj = JSON.parse("{ prop: 'val' }"); // parsedObj is any

Fixes #

updated

parse(text: string, reviver?: (key: any, value: any) => any): any;

to

parse<T = any>(text: string, reviver?: (key: any, value: any) => any): T;

It looks like you've sent a pull request to update our 'lib' files. These files aren't meant to be edited by hand, as they consist of last-known good states of the compiler and are generated from 'src'. Unless this is necessary, consider closing the pull request and sending a separate PR to update 'src'.
