How can you add text to a string and then save and print it on the screen in Kaboom.js?

Question

Kia ora everyone!

I'm trying to make my own input system in Kaboom.js by adding functions like the below and adding each key to a string called i (short for input).

keyPress("j", () => { i.concat("j"); });

Then, I try and console.log i. (i do it like console.log(i);) And for some reason I get nothing. I think it's because it's not logging an update to the string?

Is there a better method I can use, and what is wrong with my program?

If your big long string is called inputString then something like this ought to come close:

let inputString = "";
k.onKeyPress("a", event => {
   inputString.concat("a");
   console.info(inputString);
   console.info(event);
});

Rather than copy this out for every different key you're probably best trying to catch all keypresses and then check the properties of the event to determine if it's a relevant key, not an arrow key etc..
