Tell us what’s happening:
why does this program does’nt satisfy the 4th problem

Your code so far


function dropElements(arr, func) {
for(let i = 0; i < arr.length; i++){
  if(func(arr[0])){
    break;
  }else {
    arr.shift()
  }
}


return arr;
}

dropElements([1, 2, 3], function(n) {return n < 3; });

Challenge: Drop it

Link to the challenge:

2

The length of the array is changing as you loop, which means your loop does not do what you expect.

3

Just declare a variable with initial length of the arr,
and run for loop with that variable

As the arr is changing, your loop is terminating without traversing whole arr

Though, the fact that the for loop iterator variable i is never used is an indication that a for loop is not the best fit for this challenge. You can get a shorter code and simpler logic with a while loop.
