Coding Best Practices

Language Agnostic

• Avoid long chains of if statements (switch cases are ok)

• Avoid nested ternary operations - if a nested ternary only has 2 outcomes it can be written as one ternary

• Break up code into reusable functions

• Comment your code

• Have meaningful names for variables, classes, components, functions, methods, etc

• Avoid massive functions/components

• Use object oriented programming whenever possible

• Create documentation for your projects in confluence

• Handle exceptions

React

• All state hooks should be right after the constructor, then stack useEffects, followed by component functions, and finally the JSX return statement when possible.

• Avoid writing extensive logic into useEffects write as functions that can be called in the useEffect when possible

• Don't use redux or the database to hold information only being used within one component

• When writing supporting components write them to be ambiguous so they have the potential to be used outside of application they were created in.

Python

• Create a virtual environment using MinConda or MiniForge

• Don’t import * from my_package

• Create classes instead of functions

• Utilize pytest

• Don’t alter sys.path

• Create an __init__.py file if you’re creating a python module (only used via importing)
