Front End Web Development Techdegree Student 21,661 PointsWhy this code won't work?
I am trying the following
const numbers = [1,2,3,4,5,6,7,8,9,10];
const no2 = numbers.filter( (number)=> {number !== 2});
console.log(no2);
it returns an empty array, but when I do
const numbers = [1,2,3,4,5,6,7,8,9,10];
const no2 = numbers.filter( number=> number !== 2);
console.log(no2);
it return the array without 2, why brackets make such a difference and what?

Without the brackets the value after the arrow gets returned by default.
const numbers = [1,2,3,4,5,6,7,8,9,10];
// This will work
numbers.filter( (number)=> { return number !== 2});
numbers.filter( (number)=> number !== 2);
// This wont work
numbers.filter( (number)=> { number !== 2});
