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 describe well what they are for and adhere to our glossary
• avoid magic numbers (unexplained numeric literals); prefer named constants instead
  (enforced partially by ESLint: no-magic-numbers, see eslint configuration)
• 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 such as classNames, template literals are preferred
• keep lines readable
  (enforced partially by ESLint: max-len, see eslint configuration)
