When programming, one sometimes get lost too much in the day to day work and forgets the big picture. The big picture usually is that one’s code is part of a larger component, which is part of a product, which is in turn part of a line of products or tools of a company. Ultimately, each line of code matters a lot to the success of an organization.
It appears that having some emphasis on a clean codebase to as much an extent as practically possible is crucial. If the code is readable, it can be easily understood by the next developer who may be charged to fix bugs with it.
Also, in turn, reading the code written by others is a valuable and educational exercise for any developer.
