Script Preparation code:

var a = "FOO (BAR)";
var b = "foo bar 2";
var locale = "en";

var randomArray = Array(200).fill().map(
    () => Math.random().toString(36).replace(/[^a-z]+/g, '').substr(0, 30)
)

var collator = new Intl.Collator(locale);

Tests:

check localeCompare
a.localeCompare(b, locale) === 0
check collator
collator.compare(a, b) === 0
sort localeCompare
[...randomArray].sort((a,b) => a.localeCompare(b, locale))
sort collator
[...randomArray].sort(collator.compare)
