TypeScript and ECMAScript Next support

[melonfarm2]

This issue was created by viewing the 1748 comments in CSF files support.

The tsx example in markdown does not work with some features in typescript. There is a Syntax error with reserved word functions such as 'type' and 'interface'. So I'm going to use @babel/parser instead of acorn as a script parser. What should I do with the config file(tsconfig or stylieguide.config)

We haven't solved this problem for three days. Please Help..

Thank you.
