It says that PI equals 3.14 but its still an error? why?

Tell us what’s happening:

Your code so far


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


  // change code above this line
  try {
    MATH_CONSTANTS.PI = 99;
  } catch( ex ) {
    console.log(ex);
  }
  return MATH_CONSTANTS.PI;
}
const PI = freezeObj();

but PI is not the object. it is an attribute on an object. Thus, you can’t actually freeze PI (though my gran used to freeze pie all the time).

PI isn’t object. It’s a property of a object called MATH_CONSTANTS. In order to freeze object from mutations you need to pass an object not its properties. So it should be Object.freeze(MATH_CONSTANTS);
