JavaScript

Tell us what’s happening:

This challenge doesn’t seem to be difficult but I’m confused,
could smbd tell me what’s wrong with my code?

it writes bellow:

// running tests
myVar = myVar + 1; should be changed
// tests completed

but, as you can see it’s been changed

Your code so far

`js

var myVar = 87;

// Only change code below this line
myVar = ++myVar;

`

The challenge explain the shortcut ++ which increments the value to which is applied
For example a = a + 1 is equivalent to a++

The thing is that your syntax is wrong. This line myVar = ++myVar is incorrect.
It should be like this myVar += 1 or myVar++ or ++myVar.
My guess is that you need to use the first solution I proposed. :vulcan_salute:
