What is the best way to execute an inline function two times in a row

I'm currently utilizing Gametime.js to create a real-time world chat feature.

All messages are kept in a database for storage.

Interestingly, PubNub, which is used by Gametime.js, seems to require messages to be sent twice for them to actually go through.

Is there a way to execute a function twice without using a loop?

I've attempted the following method:

for (let i = 0; i < 2; i++) { gametime.run("msg", [msg]) }

While this solution works, I find myself needing to do it frequently throughout my script. Is there an alternative approach that doesn't involve a for/while loop?

Here's what I aim to accomplish with an example:

// can't use a for loop here
function example(msg) { doSomething(), doSomethingElse, {{run twice}}, done() }

javascript function loops pubnub

If you find yourself needing to run a function twice, one solution is to create a separate function specifically for that purpose:

function runTwice(callback) {
  callback();
  callback();
}

runTwice(() => console.log('hello'));

However, the need to execute a function twice may indicate an underlying issue in your code that needs to be addressed elsewhere.

To address the issue of calling the run method twice, one approach is to overwrite the run method. By doing this, you can easily revert back to the original code if a fix is implemented.

gameTimer.oldRun = gameTimer.run;

gameTimer.run = (...arguments) => {
  this.oldRun(...arguments);
  this.oldRun(...arguments);
};

However, it's important to consider potential complications if internal methods also call the run function. In such cases, creating a separate run2 function may be a viable solution:

gameTimer.run2 = (...params) => {
  this.run(...params);
  this.run(...params);
};

Restoring the original functionality is straightforward with a simple find and replace operation.
