Variables as parameters functions

1

Hi I’m new to JS and coding, so apologies in advance for a rookie question, but is it possible to use variables as parameters? Thanks guys.

Yes it is possible. here’s an example

let variable1 = "hello";

function alertTheUser(message) {
  alert(message);
}

alertTheUser(variable1); //alerts with text hello

It will just find the variable and see the value of the variable and use it. You can put a lot of stuff inside a parameter. You can put functions as parameters. You can learn more of it here:

Thank you! I really appreciate the annotated code as well! I’ll read through W3Schools as it seems like they have a lot on the basics of code!

The quality of the information on W3Schools is hit-and-miss (although it’s much better than it used to be), but the “try it yourself” widgets are great for fiddling with small amounts of code.

I wasn’t trying to criticize! I just wanted to give @donchan91 a heads-up that their mileage may vary depending on what they’re looking up. :smiley:
