Increment a Number with JavaScript..i couldnt complete it

// Only change code below this line
var myVar = 87
myVar ++ ;
//check the mistake

Link to the challenge:

You don’t need to declare another myVar and assign it to a number.

All you need to do is just increment the variable myVar like you did on the last line. But just make sure there is no space between myVar and ++.

i have tried it

The tests are being too picky. The test do not like the space between ++ and ;

thanks a lot …I finally got the answer
