Functional Programming: Avoid Mutations and Side Effects Using Functional Programming

Can someone point out where I’m going wrong and advise me what I need to do to solve the challenge.

Your code so far


// the global variable
var fixedValue = 4;

function incrementer() {
// Add your code below this line
return fixedValue + 1;

// Add your code above this line
}

var newValue = incrementer(); // Should equal 5
console.log(fixedValue); // Should print 4

Hey @OwainBennett,

You don’t need to create a variable here:

The challenge clearly asks you to only change to code inside the comments, but you tinkered with the rest of the code causing it to fail. It’s fine to console.log(); outside the comments, but don’t put anything outside the comments if not said so, because there is probably an important part of the code that checks for specific parts.
