Coding patterns

• Treat most data like it is readonly: do not modify objects or arrays in place, instead make a copy of the data and modify the copy using patterns like object spread or array spread.
• If you need to modify data, make a copy of the data and modify the copy.
• If you need to modify data in a way that is not supported by the data structure, use patterns like object spread or array spread to modify the data.
• Try to use functional patterns like map, filter, etc (but not reduce, it is too complicated).
• Avoid using let or var to declare variables, instead use const.
• Avoid using forEach to iterate over or create arrays, instead use map or filter.
• Avoid complex ternary operators, instead use if statements.
• For more complex logic, use functions to encapsulate the logic, rather than using let.
• Avoid explicitly casting types with as, instead use type inference, and/or use satisfies to assert the type of the data.
