Tell us what’s happening:

Thx guys, Ive seen a bunch of giant codes on forums. but for its work. I would like to know if a short function like that is safe. THX omw studying code

Your code so far

function findElement (arr,funct){
  
  for(let search of arr){
     if(funct(search)){
      return search;
    }
  }
}

let fint = findElement([1, 3, 5, 8, 9, 10], function(num) { return num % 2 === 0; });
console.log(fint)

Not all functions need to be super big lines of code. Sometimes something small like that works just fine.

Length does not equal safety.

May I ask a question? It would be possible to solve this test with the basic for loop? The “basic” loop i mean for(let i=0; i<arr.length; i++)… Thank you for any reply.

Hi @Ariyia

Just about anything is possible with code, and there are may approaches and methods you can use. Give it a go.

Happy coding
