JAVASCRIPT II - #1

array-methods.js
They were looking for just the first and last in a string not an object, but it's pretty close

Callbacks.js
You wrote the functions but missed the invocations.

Remember .pop() is destructive and permanently alters the arrays. This will work but not repeatedly.

Your contains function needs some breaks around the if and else to help destinguish them. The result should be declared before the if statement, and in fact outside the for loop.

what you wanted to make here was:

function contains(item, list, cb) {
  // contains checks if an item is present inside of the given array/list.
  // Pass true to the callback if it is, otherwise pass false.
let result = false;
  for(let i = 0; i < list.length; i++) {
    if(list[i] === item)
    result = true;
  }
  cb(result);
}```
if you're trying to do it the way I think you are.

Closures = 😐 but not because you didn't successfully make one

Overall keep up the hardwork!
