"Create a function named returnValue that accepts a single argument (you can name it anything), then immediately returns that argument."

Let me break this down a bit:

  • "Create a function named returnValue": This part you've already done, you defined a function called returnValue
function returnValue(){

  • " that accepts a single argument (you can name it anything)": We give a function a parameter that let's it accept an argument by adding that parameter name inside the parens (). I'm going to call this paramater value.
function returnValue(value) {

  • "then immediately returns that argument.": We can return things from a function with the return keyword, and it will return whatever is after it on the same line. In this case, we're just going to return whatever argument was passed in to the value parameter.
function returnValue(value) {
  return value;

So if someone called returnValue(5) this would just return the number 5. If we ran:

var result = returnValue(5);

It would print "5" to the console.
