Hello All,
Wondering how to refactor this if possible
const numbers = [1,2,3,4,5,6,7,8,9,10];
numbers.filter(number => number % 2 === 0);
I'm wondering since I have number => number can I do something fancy with number so I wont have to write it twice (thinking ES6)

If you don't feel clarity is seriously compromised, you can make it a bit more concise with a single-letter argument and a logical test instead of an equality comparison:
numbers.filter(n => !(n % 2));
