I would just like to place another vote to merge this PR. I would love to use this package in production but can't due to this error.

I would just like to place another vote to merge this PR. I would love to use this package in production but can't due to this error.

I yoinked some code from the changes in this pr, but I just overrode the clean method to fit my needs. Kinda a pain in the behind if you have multiple filters but guess this is all we can do unless we want to fork and make our own... or wait.

let customFilter = new Filter({
    placeHolder: "*",
});
customFilter.clean = (string) => {
    try {
        const splitMap = string.split(ProfaneFilter.splitRegex).map((word) => {
            return ProfaneFilter.isProfane(word) ? ProfaneFilter.replaceWord(word) : word;
        });
        if (splitMap.length < 2) return string;
        return splitMap.join(ProfaneFilter.splitRegex.exec(string)[0]);
    } catch (e) {
        return string;
    }
};
customFilter.clean("you are a meanie");

Would love this PR to be merged to prevent crashing on strings like :)

or like this ...

import BaseBadWordsFilter from 'bad-words';

class BadWordsFilter extends BaseBadWordsFilter {
  private readonly splitRegex!: RegExp;

  clean(string: string): string {
    try {
      const joinMatch = this.splitRegex.exec(string);
      const joinString = joinMatch?.[0] || '';
      return string
        .split(this.splitRegex)
        .map(word => {
          return this.isProfane(word) ? this.replaceWord(word) : word;
        })
        .join(joinString);
    } catch (e) {
      return string;
    }
  }
}

This really needs to be addressed the Library is poor without it
