Tell us what’s happening:
Your code so far
var myVar = 87;
// Only change code below this line
var myVar = 87;

Hi 
.
myVar = 0;
Increment a number with ++.
Decrement a number with --.
But :
myVar = myVar + 1;
// Output 1.
is not equal to :
myVar = myVar++;
// Output 0.
Because the ++ is checked after the assignment.
You can do :
myVar = ++myVar;
// Output 1;
When you’re using ++ or --, the value itself is modified.
So = is not required to assign the value.
The best practice is :
myVar++;
// Output 1.
i did it like this
var myVar = 87;
// Only change code below this line
var a = 1;
var myVar = 87+a++
and the outcome is 88 but it says i had to use the operator++
Yes, you have to use the “best pratice” I wrote above for the exercice.
