Prevent Object Mutation error

Tell us what’s happening:
I used the Object.freeze on it and everything seems to be working well. The last test that says PI equals 3.14 isn’t passing . In the console or test box it says PI equals 3.14. is this a glitch or did I mess up?

Your code so far

function freezeObj() {
  "use strict";
  const MATH_CONSTANTS = {
    PI: 3.14
  // change code below this line

  // change code above this line
  try {
  } catch( ex ) {
const PI = freezeObj();

So the function you are supposed to be learning about has the following syntax:

Looking at the line you added above, do you see what is missing?

I will leave you here…

yeah I wasn’t sure if I had to declare that parameter, thanks for the help
