I am not sure how to modify this to get the outcome?

Let’s update the incrementer function to clearly declare its dependencies.

Write the incrementer function so it takes an argument, and then returns a result after increasing the value by one.

Your code so far


// The global variable
var fixedValue = 4;

// Only change code below this line
function incrementer () {


// Only change code above this line
}

Remember to read the directions: Modify it so it takes an argument, and return the argument plus one.

I did it like this but it doesn’t work.:confused:

// The global variable
var fixedValue = 4;

// Only change code below this line
function incrementer (value) {

 return value + 1;
// Only change code above this line
}
var newValue =  incrementer (fixedValue );

You added something extra on the end.

I think I need to omit var newValue

In the code, it says “Only change code above this line”. You don’t need to call the function, you just need to make it.
