I am making a filter for a chat room I own.
I was succesful in having it turn NSFW words into a bunch of symbols and astericks to censor it, but many people bypass it by simply putting a backslash, period, or other symbol/letter after it because I only put in the words without the punctation and symbols. They also come up with a bit more creative methods such as eeeNSFWeee so the filter doesn't count it as a word.
Is there a way to make it so that the filter will select certain characters that form a word in a string and replace them (with or without replacing the extra characters connected to the message)?

The Filter is made in javascript and Socket.io

Filter code:

    const array = [
  "NSFW",
  "Bad Word"
  "Innapropiate Word"
];

message = message
  .split(" ")
  .map((word) => (array.includes(word.toLowerCase()) ? "$#!%" : word))
  .join(" ");

For an example if somebody typed "Bad Word" exactly like that (caps are not a problem), it would censor it succesfully.
But if somebody typed "Bad Word." that would be a problem because since it has a period it would count it as a different word, thats what I need fixed.
