How to move multiple elements to the beginning of the array in JavaScript?

We have to write a function that takes an array and any number of strings as arguments. The task is to check if the strings occur within the array. If it does, we have to move that particular to the front of the array.

Therefore, let’s write the code for this function −


const arr = ['The', 'weather', 'today', 'is', 'a', 'bit', 'windy.'];
const pushFront = (arr, ...strings) => {
   strings.forEach(el => {
      const index = arr.indexOf(el);
      if(index !== -1){
         arr.unshift(arr.splice(index, 1)[0]);
pushFront(arr, 'today', 'air', 'bit', 'windy.', 'rain');


The output in the console will be −

[ 'windy.', 'bit', 'today', 'The', 'weather', 'is', 'a' ]
