Reserved words

There are a good number of words reserved in JavaScript that cannot be used for variable names. Here is a list of most of them:

abstract
arguments
await
boolean
break
byte
case
catch
char
class
const
continue
debugger
default
delete
do

double
else
enum
eval
export
extends
false
final
finally
float
for
function
goto
if
implements
import

in
instanceof
int
interface
let
long
native
new
null
package
private
protected
public
return
short
static

super
switch
synchronized
this
throw
throws
transient
true
try
typeof
var
void
volatile
while
with
yield

 

These are always in lowercase, and if you were to attempt to use one of these words as a variable name, the program would show an error.
