Add links to the TypeScript playground

[orta]

The TS playground will get the types for react if you include the import React from "react" and set the right compiler flags

an example

A lot of large examples could have a corresponding playground link then.

Hey orta, will do

I'd like to take this one on!

all yours!

Started this today. Should have a PR open tonight or this weekend. One question for @orta

I'm getting an error in the playground for Promise.finally.

Things I've tried:

1. Setting the target to ES2018

My guess is that I need the lib to include es2018 in the config options? But I don't see that available. Any ideas?

great job joe!
