parseFloat() inside forEach() not working

Question

can anyone help me understand why this code doesn't work? Don't know where I'm going wrong.

let ratings = ["8.8", "8.6", "9.0", "8.3"];

ratings.forEach(rating => {
return parseFloat(rating)}
);

I just get undefined.

note that forEach returns undefined so use Array.map() instead. — zb22, Jul 30 '18 at 18:32
`forEach` is an optimized `map` since its only for side effects and returned values are never used. `ubdefined` is correct result. — Sylwester, Jul 30 '18 at 20:19

Your program is not working since your forEach() is not storing the result anywhere. And it would be better to use Array.map() in this case :

:

let ratings = ["8.8", "8.6", "9.0", "8.3"];

ratings = ratings.map(a=> parseFloat(a));

console.log(ratings);
