```
**Your code so far**
```

```
function freezeObj() {
const MATH_CONSTANTS = {
PI: 3.14
};
// Only change code below this line
Object.freeze(MATH_CONSTANTS);
// Only change code above this line
try {
MATH_CONSTANTS.PI = 99;
} catch(ex) {
console.log(ex);
}
return MATH_CONSTANTS.PI;
}
const PI = freezeObj();
