Discussion on: Array Iteration for Beginners

[Frank Wisniewski]

we are in the year 2022!!

const greaterThanThree = num => num > 3

[FJones]

To be fair (despite the formatting), it does say "for beginners", and the prevailing thought is still that beginners don't like arrow functions.

That said, if we want to do this, might as well do it right:

const greaterThan = than => num => num > than;
const greaterThanThree = greaterThan(3);

[Frank Wisniewski]

Well then I'd rather do it that way

const isGreaterThan = num => value => value > num
let list = [1,2,3,4,5]    
console.log(
  list.filter(isGreaterThan(3)) 
)
