What is ‘define’ used for in JavaScript (aside from the obvious)?

by

I can’t say for sure without seeing the entire script, but it’s likely to be the define function from RequireJS, in particular the “define with dependencies” form of that function. It is used to define a “module”:

A module is different from a traditional script file in that it
defines a well-scoped object that avoids polluting the global
namespace. It can explicitly list its dependencies and get a handle on
those dependencies without needing to refer to global objects, but
instead receive the dependencies as arguments to the function that
defines the module.

And the “define with dependencies” form of define is described as follows:

If the module has dependencies, the first argument should be an array
of dependency names, and the second argument should be a definition
function. The function will be called to define the module once all
dependencies have loaded. The function should return an object that
defines the module.
