What does this code mean? I need an explanation

[srdjanmutlak]

Can someone please explain how this code works?

I understand that it's a page object section code. I don't understand why would someone create this kind of code? What would happened if "false" was "true"? Would Cypress then go automatically into the part after ":" ?

Please explain if you saw this before somewhere or if you understand the syntax just by looking at it.

Here's where the full code is from:

Hi,
the question mark is a shortcut for "if" - for example, for the code about entering the description, it would read like:

if (description) {
   this.getInputField('description').clear().type(description)
} else {
   this.getInputField('description').clear()
}
