I think I wrote the same as Guil did but I'm getting an error whenever I copy and paste into the console.
function getArea(width, length, unit) {
const area = width * length;
return ${area} ${unit};
}
getArea(10, 20, 'sq ft');

Full Stack JavaScript Techdegree Student 4,646 PointsGlad you guys figured it out. For anyone else reading, I just wanted to provide clarification on why it seemed to only work when pasting the entire code with the function definitions and calls. If you start a web console in a fresh browser window without your code executing in the page, your function will not be defined in the console.
I imagine the error you probably got at the time was something like:
ReferenceError: Can't find variable: getArea
You had to paste the function definition for getArea() in the console to define it, and only then could you call it. If I had to guess, you may have not updated the <script> tag inside index.html with js/multiple-args.js and saved the file (happens all the time). If the <script> tag was executed it would have defined the getArea() function already so you can call it as many times as you want without a ReferenceError.

Full Stack JavaScript Techdegree Student 1,427 PointsHi,
please use Markdown Cheatsheet Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.
when you use a template literals you should start with backticks like that.
return `${area} ${unit}`

Front End Web Development Techdegree Graduate 14,657 PointsThank you for your reply. The back ticks were there originally. I don't know why they disappeared after I copied and pasted the code to Treehouse Forum. My code seems to work fine now in the console after I pasted the entire code to the console. Thank you!

Full Stack JavaScript Techdegree Graduate 14,490 PointsI had the same issue! But it worked after pasting it all - including the function definition - into the console like you said. Thanks!
