Question

ibrd

I should change its position to the beginning. can I do this using JavaScript? how can I do this using string.

Answer 1

I think this will solve your problem

const changeLetter = (val /* string value */, index /* index of the letter (i in this scenario)*/) => {
  let temp = val.split('');

  temp.splice(index, 1);
  temp.unshift(val[index]);

  return temp.join('');
}

const val = 'bird';

console.log(changeLetter(val, 1));
