Replacing multiple words in a message with other words?

I am trying to make my Discord bot replace various words in a message with other words, but I can't seem to figure out how to do it for more than 1 word.

Let me give an example:

I want to replace the '!say' with nothing

I want to replace 'llama' with 'ogre'

I want to replace 'john' with 'johnny'

So, I want the bot to replace these words with the other words. But I can only figure it out with doing one replacement, otherwise it repeats the message over and each with the different change.

Here's the code I got at the moment for this

client.on("message", message => {
if (message.content.startsWith("!say")) {
message.channel.sendMessage("I say: " + message.content.replace('!say ','' + '\n'))
};
});

Anyone know how? Sorry if this is super confusing :(

I'd make an object whose keys are the words you want to replace, and whose values are their replacements. Then you can construct a regular expression by joining all keys together, and use a replacer function to look up the appropriate replaced value on the object:

const replacements = {
  '!say': '',
  llama: 'ogre',
  john: 'johnny'
};
const pattern = new RegExp(Object.keys(replacements).join('|'), 'g');
client.on("message", message => {
  const replacedText = message.content.replace(pattern, key => replacements[key]);
  // use replacedText
});


const replacements = {
  '!say': '',
  llama: 'ogre',
  john: 'johnny'
};
const pattern = new RegExp(Object.keys(replacements).join('|'), 'g');

const input = '!say foo bar llama baz john buzz';
const replacedText = input.replace(pattern, key => replacements[key]);
console.log(replacedText);
