Note: I am very new to Javascript.
I am trying to make a system in my chatroom where if you type a certain word (password) into the chat it will edit their username to include a special mod tag. I am doing this because we don't have profile systems and it is the best solution I could come up with. However I ran into a problem, I don't know how to edit a string's data (in this case the username) to add something to it with a function. If anybody could help it would be much appreciated.
Code:
if(data.message = password) {
username.data + "Mod"
}
Extra question: In the above example, would having if(data.message = password) make it so that if it contains the variable (password) it would change it, or would it just be if they typed "password" that it would change it?
Edit: I have moved all my code to a github repository to show people it, you can find it here. Most of the chat itself is Javascript, and if you have any questions about what a certain thing does just ask in the comments!
= means assignment, == and === are equality comparasins (look up the difference)+=== password means "true if data.message is exactly equal to the value of the variable password". If you want to see if the variable password is contained in the string, do data.message.contains(password)const checkForMod = (data, username) => {
if (data.message == password) {
username.data += "Mod";
}
}
You need to assign the new value back to the variable like this:
if(data.message == password) {
username.data = username.data + "Mod";
// or using template string
username.data = `${username.data}Mod`;
}
I assumed username is an JSON object.
Answer to extra:
You need to use == (just the value) or === (strictly check the data type and value) in if condition. If the data.message is exactly the value of password then the condition is satisfied.
If you want to check if the password is a substring (the message contains value of password anywhere in the message) then you need to use String.prototype.includes. demo below:
if(data.message.includes(password)) {
username.data = username.data + "Mod";
// or using template string
username.data = `${username.data}Mod`;
}
If you have more doubts, you can comment below. I'll update this answer.
Edit:
After reading your comment, I'm adding below sample to show you how above code works:

const password = "qwerty1234"
const data = {
message1: `this is my ${password}`,
message2: password,
}
const username = {
data: "chankruze",
}
console.log(username.data);
if (data.message1.includes(password)) {
console.log("password found in side data");
username.data += "mod";
}
console.log(username.data);
if (data.message2 === password) {
console.log("exact match");
username.data = `${username.data}mod`;
}
console.log(username.data);
