Documentation for JS 52 Languge feature support?

[Kent Williams]

I've done a port of the Typescript Compiler to embed in our
application.  I need to support a Node-style 'require', but I'm not sure
what my Typescript target should be to take advantage of the language
features.

Any pointers? The release notes are empty:

I combed through MDN at one point to produce this summary for the NEWS file of my project: https://gitlab.gnome.org/GNOME/gjs/commit/c1525a7a48fcd109022146be657844cde2c8c9dc
This may be the same info that you're looking for.
