Find the index of the array element you want to remove using indexOf, and then remove that index with splice.
The splice() method changes the contents of an array by removing existing elements and/or adding new elements.
const array = [2, 5, 9];
console.log(array);
const index = array.indexOf(5);
if (index > -1) {
array.splice(index, 1); // 2nd parameter means remove one item only
}
// array = [2, 9]
console.log(array);javascript - How can I remove a specific item from an array?
