List of reserved keywords

[chinhodado]

Is there a list of reserved keywords for Typescript somewhere? I have looked around and couldn't find it, even in the language specification.

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 (@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
with

Strict Mode Reserved Words
as

interface
let
package
private
protected
public
static
yield

Contextual Keywords

Also namespace, maybe async and await eventually.

@DanielRosenwasser looks like this should have a wiki page

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.
