Hey @nhymfa31
When you declare a variable in JS you have to assign a value to it using the assignment operator otherwise it will be undefined so like what is happening here you are incrementing an undefined variable.

@nhymfa31

let myVar ++ 87;

This will result to NaN
so just assign the variable to a value like so

var a=23;

Then you can increment the value,either by doing this

a = a + 1;

Happy coding

Welcome to the community @nhymfa31 !

I believe the lesson wishes us to use the increment operator

You can easily increment or add one to a variable with the ++ operator.

For example as taken from the lesson.
i = i + 1
would be equivalent to i++
using the increment operator.
This removes the need for the =

I hope this helps you.
