If your goal is to sort a list of strings, disregarding accents

['André', 'Álister', 'alan'].sort(new Intl.Collator('pt-BR').compare)

Or just to be safe

['André', 'Álister', 'alan'].sort(new Intl.Collator('pt-BR', {sensitivity:'base'}).compare)

Other variant could be..
const removeAccents = (str) => { return str .toLowerCase() .normalize("NFD") .replace(/[\u0300-\u036f]/g, ""); };
