This is kind of a cop out IMO. There's got to be some entry point to gain visibility into the code, put a breakpoint there, run in debugger, single step/step over until you get the basic idea of how it flows. I'm speaking from experience, I inherited a project based on TaxiAnytime, aka "Uber App Clone Source Code". What a complete clusterfuck, obviously written in as incomprehensible a style as possible to create attachment sales for customization. In the PHP/Laravel code three widely used patterns stand out, the "single return statement pattern", which obviously creates the pyramid from hell. In every method. Add to that, the 700+ line methods. Everywhere. And the icing on the cake, I'm going to invent the term "WET" here to describe it. That means the opposite of DRY. Did I say three? WET has the knock-on effect of anti-encapsulation. I set out to reverse those patterns where I needed to make changes. In about 2 months as a single man team, I had a handle on it and was extending the app. A team of 5 should be able to make short work of it if they can get over the NIH and YUK factors. And yes, beware the rewrite. Coding always seems like it is easy. Until you need a resilient functioning system.
