Tell us what’s happening:
My code executes 5/6 requirements except for the output below. Can’t seems to figure out what’s wrong, tried adding else {return }. Got that checked but the rest not. Hmmmm…

Your code so far


function dropElements(arr, func) {
var x = [];
for (let i = 0; i < arr.length; i++) {
if (func(arr[i])) {
  x.push(arr.indexOf(arr[i]));
  if (x.length === 1) {return arr.slice(x)} 
} 
}
};

console.log(dropElements([1, 2, 3, 7, 4], function(n) {return n > 3;}));

Your idea with returning is pretty close, only thing is, if you do this with an else, it gets returned to early, the loop stops and not all numbers get checked …

Hey, thanks for your respond.

Too early? Could you elaborate?

Cheers!

Go it!! thanks!

  var x = [];
  for (let i = 0; i < arr.length; i++) {
  if (func(arr[i])) {
    x.push(arr.indexOf(arr[i]));
    if (x.length === 1) {return arr.slice(x)} 
  }
}
if (x.length === 0) {
  return [];
}
};

I’ve added another if statement…
