Can the second parameter of a RegExp be to match the whole word that is given in the first parameter?

new RegExp(words, `g`)

I have tried everything but it does not work. Does someone know how to make this happen?

UPDATE:

I have a list of words that I want to match in a paragraph. I use .replace(/\b(dog|cat|pet)/gi, replaceWords) to match exactly the words in the first parameter.

The problem is is that I have more then 300 words. How can I make the RegExp match the whole word in the second parameter?

Try word boundary `\b word \b` – Asons Jul 02 '18 at 12:45
what is `words`? – dfsq Jul 02 '18 at 12:46
The second parameter contains the flags. What do you mean by "match the whole word" ? Can you add some examples ? – Seblor Jul 02 '18 at 12:46
