How can I decline different words in js depending on the counter?

Question

JavaScript

Good morning everyone! I have a counter that counts the number of selected input[checkbox].
But the words are 2 brands, 5 brands, etc. But I have several elements where my counter is substituted.
It's not a problem to do it, you can create an array of words and insert the number you need depending on the range of the number.
But how to implement with different words?
