Why localize a function?

[Calikid92]

I've always used functions without localizing it, what's the point?

[Whiterabbit]

If you don't, and another addon creates a function with the same name, it gets overwritten.

[Calikid92]

Ok, that makes sense.

[Rubat]

And sometimes you want the function to be inaccessible from other files.

If your function is in a table it doesn't matter too much, but global functions should generally be avoided.
