javascript destroy array with single code example

Example 1: How can I remove a specific item from an array

const array = [2, 5, 9];

console.log(array);

const index = array.indexOf(5);
if (index > -1) {
  array.splice(index, 1);
}

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

Example 2: empty array js

let list = [1, 2, 3, 4];
function empty() {
    //empty your array
    list.length = 0;
}
empty();
