Increment a Number with JS

JavaScript

Tell us what’s happening:

Your code so far


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

Yes, ++myVar, should also work, but I guess the test is set up to accept it if the operator follows the variable, like in the example.

I agree with @kevinSmith, it’s probably got to do with how the testing environment is expecting to see the answer. However, it is worth noting that ++var and var++ aren’t technically the same.

++var returns the immediate increment of the var whereas var++ initially returns the original variable without being incremented
