console.log(userName);I want to give the username a meaningless word at the end which is in randomWord. I would like it to be like frank440donec and give each username a different meaningless word at the end, but it gives all the names a different meaningless word except for two which are assigned the same meaningless word.
If the aim is to randomly assign -- avoiding duplicates -- from a set of names, then a good solution is to shuffle the names...
// names must be at least the length of the people array
const names = ['donec', 'pellentesque', 'facilisis', 'potenti'];
shuffle(names);
const userNameGenerator = (person, index) => {
const randomWord = names[index];
const ageXValue = person.age*person.value+300;
return `${person.name}${ageXValue}${randomWord}`;
}
// shuffle based on https://stackoverflow.com/a/12646864/294949
function shuffle(array) {
for (let i = array.length - 1; i > 0; i--) {
const j = Math.floor(Math.random() * (i + 1));
const temp = array[i];
array[i] = array[j];
array[j] = temp;
}
