• Always prefer best practices when writing code.
• Write using concise, legible, and easily maintainable code.
• Avoid repetition where possible, but not at the expense of code legibility.
• Type assertions are an absolute last resort. In almost all cases, they are a crutch that leads to brittle code.
• This codebase has extensive eslint autofix rules and IDEs are configured to use eslint as the format on save tool. Run eslint --fix instead of manually figuring out whitespace fixes or other trivial style concerns. Review the results and correct any remaining eslint errors.
• Take advantage of TypedArray subarray when appropriate.
• The size and pos properties of Rectangle share the same array buffer (subarray); they may be used to set the rectangles size and position.
• Prefer single line if syntax over adding curly braces, when the statement has a very concise expression and concise, single line statement.
• Do not replace &&= or ||= with = when there is no reason to do so. If you do find a reason to remove either &&= or ||=, leave a comment explaining why the removal occurred.
• You are allowed to research code on https://developer.mozilla.org/ and https://stackoverflow.com without asking.
• When adding featueres, always write vitest unit tests using cursor rules in @.cursor
• When writing methods, prefer returning idiomatic JavaScript undefined over null, unless there is a specific use-case for null.
