[Solved] Drop it, I think my answer is correct but it doesn't work on FCC

JavaScript
#1

Tell us what’s happening:
Okay, so I do these problems in VS Code, then put the answer into FCC. I don’t know if THAT’s the issue, but when I run my code in the browser from VS Code, I get all the right answers for the tests. But when I tried to run it in FCC, it says all the tests failed.

I understand that my way of doing this might be more complicated than it needed to be, but it was the first thing that came to mind.

Here is a JSFiddle of what mine does, and it works in the JSFiddle when you look at the Console.

I’m just wondering why the FCC tests are saying it failed when I am pretty sure I have a correct answer.

Your code so far


function dropElements(arr, func) {
  // Drop them elements.
  let toggle = false;
  for (let i = 0; i < arr.length; i++) {
    if (func(arr[i])) {
      console.log(arr.splice(i));
      toggle = true;
      return arr.splice(i);
    } else if (i === arr.length - 1 && !func(arr[i])) {
      console.log([]);
      arr.splice(arr.length);
      return [];
    }
  }
}

dropElements([1, 2, 3, 4], function(n) {
  return n >= 3;
}); // [3, 4]

dropElements([0, 1, 0, 1], function(n) {
  return n === 1;
}); // [1, 0, 1]

dropElements([1, 2, 3], function(n) {
  return n > 0;
}); // [1, 2, 3]

dropElements([1, 2, 3, 4], function(n) {
  return n > 5;
}); // []

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

dropElements([1, 2, 3, 9, 2], function(n) {
  return n > 2;
}); // [3, 9, 2]

#2 
      console.log(arr.splice(i));
      toggle = true;
      return arr.splice(i);

splice() modifies the array. You are calling it twice, so the array that you are returning is not the same as the one that your console prints two lines earlier.

#3

Oh jeez. That fixed it. I guess I assumed that since it was a console.log, that since the way I called it twice, it would just be the same thing, not splice it twice. Thank you! I took the console.log out and tried it again and it worked just fine.

#4

If you want to both return and console log something you need to assign it to a variable

let a = arr.splice(i);
console.log(a);
return a;
