You’re missing a closing curly bracket at the end of the function calculateWeight.

umm but i dont need to curly bracket here !!

You need as many closing brackets as opening ones - otherwise you get a syntax error. That is the case here.
You have

const calculateWeight = (earthWeight, planet) => { // <-- no closing counterpart
