Syntax error Segregate all 0s on right and 1s on left in JavaScript

Segregate all 0s on right and 1s on left in JavaScript

We have an array of Numbers that contains 0, 1 and some other numbers. We are required to write a JavaScript function that takes in this array and brings all 1s to the start and 0s to the end

Let's write the code for this function −

Example

const arr = [3, 2, 1, 8, 9, 0, 1, 9, 0, 2, 1, 0, 2, 0, 1, 0, 1, 1, 4, 0,
3];
const segregate = arr => {
   const copy = arr.slice();
   for(let i = 0; i < copy.length; i++){
      if(copy[i] === 0){
         copy.push(copy.splice(i, 1)[0]);
      }else if(copy[i] === 1){
         copy.unshift(copy.splice(i, 1)[0]);
      };
      continue;
   };
   return copy;
};
console.log(segregate(arr));

Output

The output in the console will be −

[
   1, 1, 1, 3, 2, 8, 9,
   1, 9, 2, 2, 1, 1, 4,
   3, 0, 0, 0, 0, 0, 0
]
