let countries = ["Uganda", "Sweden", "Thailand", "Zambia", "India", "America"]

And now our task is to sort the countries in alphabetical order, so to do that we will use the sort() methods as:

let countries = ["Uganda", "Sweden", "Thailand","Zambia", "India", "America"]

const sortedCountries = countries.sort()


[ 'America', 'India', 'Sweden', 'Thailand', 'Uganda', 'Zambia' ]

By default the sort() methods sorts the elements in an array alphabetically in ascending order. However to sort it in descending order we have to use the compare function and pass it in the sort() method.

let countries = ["Uganda", "Sweden", "Thailand","Zambia", "India", "America"]

countries.sort((a, b) => {
    if (a > b) return -1;
    if (a < b) return 1;
    return 0;



[ 'Zambia', 'Uganda', 'Thailand', 'Sweden', 'India', 'America' ]

That's how you can compare and sort alphabets in a array in any order you like.
