User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:101.0) Gecko/20100101 Firefox/101.0
Steps to reproduce:
run the program:
var else;
Actual results:
SyntaxError:missing variable name
Expected results:
SyntaxError:Cannot use the keyword 'else' as a variable name.(JSC)
SyntaxError:Unexpected token 'else'.(V8)
It is obvious that the error is wrong variable name rather than missing variable name when i use a key word as a identifier.
It also has the same problem when i use 'arguments','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'.
