Name words are in dictionary order only. about unique-names-generator

[ShaneMcC]

This is as designed I believe. It uses the dictionaries in order and that seems desirable so that you can always ensure you get for example a coloured-animal username by using [colors, animals]

If you wanted to just use all of them, then you could do something like:

const NAME_WORDS = [...animals, ...adjectives, ...colors, ...names, ...languages];
const NAME_CONFIG = {
    dictionaries: [NAME_WORDS, NAME_WORDS],
    separator: ' ',
    length: 2,
    style: 'capital'
};
