   While you could refer to the ES6 spec to figure out a partial list, it might be better to go directly to the code for the current list. Perhaps it would be better to keep a complete list as part of the TS spec (Anders Hejlsberg (@ahejlsberg))

   Based on the code, I ripped this out for you:

   Reserved Words	Strict Mode Reserved Words	Contextual Keywords
   break	as	any
   case	implements	boolean
   catch	interface	constructor
   class	let	declare
   const	package	get
   continue	private	module
   debugger	protected	require
   default	public	number
   delete	static	set
   do	yield	string
   else	symbol
   enum	type
   export	from
   extends	of
   false
   finally
   for
   function
   if
   import
   in
   instanceof
   new
   null
   return
   super
   switch
   this
   throw
   true
   try
   typeof
   var
   void
   while
   with

   And if you want to just copy more easily:

   Reserved Words
   break
   case
   catch
   class
   const
   continue
   debugger
   default
   delete
   do
   else
   enum
   export
   extends
   false
   finally
   for
   function
   if
   import
   in
   instanceof
   new
   null
   return
   super
   switch
   this
   throw
   true
   try
   typeof
   var
   void
   while

   Also namespace, maybe async and await eventually.

   I tried a few of reserve words mentioned here on the Typescript Playground and didn't encounter any issues. IMO, the keywords should match at least those for ES6. For the later I have a list here https://github.com/crissdev/is-keyword-js/blob/master/index.js which is a list created from MDN site.
