Any other options to replace if in map?

Question

JavaScript

People, it is possible to replace if with something else, in this code

const characters = [
  'Люк Скайуокер',
  'Оби Ван',
  'Чубакка',
  'Энакин Скайуокер',
  'Хан Соло',
  'Палпатин'
];

const newCharacters = characters.map(function (character) {
  if (character === 'Энакин Скайуокер') {
    return 'Дарт Вейдер';
  }

  return character;
});

console.log(newCharacters);

Tried through slice and splice does not work. Maybe I'm doing it wrong. Is it possible to do it through the slice and splice methods?

Answer 1

return character === '...' ? '...' : character;
Or, if there are several replacements, make an object where it will be indicated who should be replaced with whom:

const replacements = {
  '...': '...',
  '...': '...',
  ...
};

const newCharacters = characters.map(n => replacements[n] || n);

Answer 2

Using splice

let characters = [
  'Люк Скайуокер',
  'Оби Ван',
  'Чубакка',
  'Энакин Скайуокер',
  'Хан Соло',
  'Палпатин'
];

const enakinIndex = characters.indexOf('Энакин Скайуокер')

characters.splice(enakinIndex, 1, 'Дарт Вейдер')
