console.log(censoredText); 
// log: isso é uma *****

In .censor() asterisks in will be used to replace the swear words.

let censoredText = profanity.censor("You piece of sH1t");
console.log(censoredText); 
// log: You piece of ****

3. Check if the string contains any swear words

Function .isProfane() return True if any words in the given string has a word existing in the wordlist.

let dirtyText = "That l3sbi4n did a very good H4ndjob.";

console.log(profanity.isProfane(dirtyText));
// log: true

let customBadwords = ['happy', 'sometext'];

profanity.addWords(...customBadwords);

console.log(profanity.isProfane("Happy day bro!"));
// log: true

The lib supports two languages they are Brazilian Portuguese and English, the defaults are Portuguese and to change this, see below.

let config = {
    language: "en-us"
};

let dirtyText = "fuck this shit";

const profanity = new Profanity(dirtyText, config)

console.log(profanity.censor());
// log: **** this ****

The config Object will be overwritten the default values.

let config = {
    placeHolder: "-"
};

let dirtyText = "fuck this shit";

const profanity = new Profanity(dirtyText, config)

console.log(profanity.censor());
// log: ---- this ----

let config = {
    wordsList: ['shit', 'fuck', 'this']
};

let dirtyText = "fuck this shit";

const profanity = new Profanity(dirtyText, config)

console.log(profanity.censor());
