Code

For both frontend/backend:

• we prefer using:
  1. our own util functions (if available)
  2. battle-tested good libraries (with decisions)
• compiler and linter should be without any warnings or errors
• keep code stupid (debugging is twice as hard as coding)
• names should be describing well what they are for and adhere to our glossary
• avoid magic numbers, prefer to use named constant instead
• avoid obviously inefficient code if more efficient solutions are available (please benchmark or ask in case of doubt)

For frontend:

• don't overuse useEffect (see You Might Not Need an Effect)
• for longer strings like classNames template literals are preferred
