How to remove a specific item from an array

In vanilla JS, to remove a specific item from an array we need to find the index of that element using the indexOf method, and then remove that index with the splice method.

const array = [8, 5, 2, 0, 9];

const index = array.indexOf(5); // index of 5
if (index > -1) { // only splice array when our item is found
  array.splice(index, 1); // second parameter means how many items we want to remove
}

console.log(array);  // array = [8, 2, 0, 9]
