Question on syntax

[TheRev]

Tell us what’s happening:
Describe your issue in detail here.

When I couldn’t get my code to pass, I cheated and looked at the answer. In the correct code, (val++) was instead (val + 1). Everything else in my original code matched the solution offered. Is there a reason why (val++) doesn’t pass the test? Is there a limitation to the (++) syntax that I am unaware of? Am I missing something more obvious? Thanks in advance for any help.

  **Your code so far**

// The global variable
let fixedValue = 4;

// Only change code below this line
function incrementer(val) {
return val++;

// Only change code above this line
}

Hi @TheRev !

You can use the increment operator and pass this challenge.
The problem is that you are using it incorrectly here.

This syntax will return the value before it increments.

@TheRev

return val++;

This is the postfix increment.

If you changed your code to use the prefix increment like this then it will return the value after incrementing.

return ++val;

You can add this console.log to your code and play around with the postfix and prefixes to see the differences.

console.log(`result: ${incrementer(fixedValue)}`)
console.log(`fixedValue: ${fixedValue}`)

hope that helps!

Did not know that. Thank you!
