Coding: Best Practices

It is important when writing software, in any language, that attention should be paid not only to the correct functioning of the code, but also to how the code is written and organised. Well written code is easier to understand, debug, maintain, enhance, and test. This can make or break a team software development project, and great emphasis is placed on adherence to coding standards and best practices in software design. It is equally important for solo developers who share their code with an Open Source community, or even when returning to one’s own code written some time in the past.

This document contains some guidelines which may be useful when programming with App Inventor, and which represent practical implementations of widely accepted programming principles.
