Challenge 1 / 2

Ultimately - whether via a manual require statement written by you or via an autoloader function - something needs to require/include a file before we can use the class that lives inside of it.

But, which option will give you better performance?

Autoloaders are always faster than manually having many require statements.

Autoloaders are usually faster than having require statements, because you don't need to include files that you don't use.

Manual require statements are always faster than autoloaders. Yes, they're annoying to write, but there is a lot of extra overhead for calling the autoload function over and over again.

Manual require statements are always faster than an autoloader function. By requiring all of the files in the very beginning, your application can quickly reference any class or function it needs.
