How do you explain code logic and assumptions?

1 Use comments and documentation

One of the simplest and most helpful ways to explain your code logic and assumptions is to use comments and documentation. Comments are short notes that you write in your code to explain what each line or block of code does, how it relates to the overall logic, and what assumptions you are making. Documentation is a more detailed and structured description of your code, its purpose, features, inputs, outputs, and limitations. Both comments and documentation can help others understand your code logic and assumptions without having to read the entire code or run it.

2 Use pseudocode and diagrams

Another way to explain your code logic and assumptions is to use pseudocode and diagrams. Pseudocode is a simplified version of your code that uses plain language and common conventions to describe the logic and flow of your program. Diagrams are visual representations of your code that show the main components, data structures, functions, loops, conditions, and interactions. Both pseudocode and diagrams can help others grasp your code logic and assumptions at a glance, without getting lost in the details or syntax of your code.

3 Use examples and tests

A third way to explain your code logic and assumptions is to use examples and tests. Examples are specific cases that demonstrate how your code works, what it does, and what it expects. Tests are checks that verify that your code behaves as expected, meets the requirements, and handles errors. Both examples and tests can help others see your code logic and assumptions in action, and validate them against the expected outcomes and scenarios.
