   var index = arr.indexOf(value);
   if (index > -1) {
      arr.splice(index, 1);
   }
   return arr;
}

// Remove all items
function removeItemAll(arr, value) {
   var i = 0;
   while (i < arr.length) {
      if (arr[i] === value) {
         arr.splice(i, 1);

let fruit = ['apple', 'banana', 'orange', 'lettuce']; 
// ^^ An example array that needs to have one item removed

fruit.splice(3, 1); // Removes an item in the array using splice() method
// First argument is the index of removal
// Second argument is the amount of items to remove from that index and on

let numbers = [1,2,3,4]

// to remove last element
let lastElem = numbers.pop()

// to remove first element
let firstElem = numbers.shift()

// both these methods modify array while returning the removed element

let numbers = [1,2,3,4]

// to remove last element
let last_num = numbers.pop();
// numbers will now be [1,2,3]

// to remove first element
let first_num = numbers.shift();
//numbers will now be [2,3]

// to remove at an index
let number_index = 1
let index_num = numbers.splice(number_index,1); //removes 1 element at index 1
//numbers will now be [2]

//these methods will modify the numbers array and return the removed element
