I’m not sure how to structure the some method. I was a bit confused on where to position it.

This is because you are using .some() method to check if your provided message string has any word given in the denyList array. You pass forbidden string elements of the denylist as regex and test if msg string has any string like regex in it through .test() method.

Happy coding :blush:

Oh, so I need to refer to the forbidden string elemeets as regex, right?

hey @tarequemahmud313

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.

hey @KoduFCC , the regex parameter can be used to reference the regex patterns inside denyList - if you use the array method on denyList inside there are regex patterns, it makes sense to call them as such
