I have code:
xxxxxxxxxx1
const text = 'WSPÓŁCZYNNIK ąęć ź - pochłaniania DŹWIĘKU test ąęć';2
3
const letters = ['ą', 'ć', 'ę', 'ł', 'ń', 'ó', 'ś', 'ź', 'ż'];4
const replacement = ['a', 'c', 'e', 'l', 'n', 'o', 's', 'z', 'z'];5
6
let result = text.toLocaleLowerCase();7
8
for (let i = 0; i < letters.length; ++i) {9
result = result.replaceAll(letters[i], replacement[i]);10
}11
12
console.log("before: " + text);13
console.log("after : " + result);My current resut:
xxxxxxxxxx1
before: WSPÓŁCZYNNIK ąęć ź - pochłaniania DŹWIĘKU test ąęć2
after : wspolczynnik aec z - pochlaniania dzwieku test aec
What is the best way to make from input string the result string:
xxxxxxxxxx1
before:2
WSPÓŁCZYNNIK ąęć ź - pochłaniania DŹWIĘKU test ąęć3
after:4
