removeAccents Removes accents from strings. Use String.prototype.normalize() to convert the string to a normalized Unicode format. Use String.prototype.replace() to replace diacritical marks in the given Unicode range by empty strings. const removeAccents = str => str.normalize('NFD').replace(/[\u0300-\u036f]/g, ''); removeAccents('Antoine de Saint-Exupéry'); // 'Antoine de Saint-Exupery'
