I’m just curious why use function parameters at all?
Why not avoid the function to begin with and just place the concatenation, as in the screen shot I provided, into the label to save code?
That’s not a great example of using a function to simplify code. I’d say it’s fine either way.

What is a good argument for function parameters?
The most obvious answer to me is that a function should handle repetitive code by reducing the number of blocks needed.
So if I find myself re-using a set of blocks, I might make it into a function. Or if I need to run those blocks over and over with different input values, I might make it into a function.
Not the function itself, the parameters.
What is the significance of having them?
Parameters allow you to run the same function multiple times with different inputs.
Let’s say I wanted to take an image url stored in Cloudinary, convert it so that the image is cropped and scaled and set to a lower file size as well, and then share that url in an email message using an API to send it. I could make the url the parameter of the function that does all of that and for any image I wanted to run through that process, I could just call the function block with that image’s url.
