+Follow these rules when you write JavaScript code:
+* Use CommonJS modules and strict mode
+* Use early return wherever possible
+* Use functional programming style, currying, higher order functions, arrow functions, destructuring, async/await, generators, etc.
+* Use onml/jsonml for creating HTML and SVG elements
+* Use style-mod for CSS styling
+
+Follow these rules when you write C code that will be compiled to WebAssembly:
+* Use C99 standard
+* Use clang and wasm-ld for compilation
+* Do not use externals libraries
+* Do not use dynamic memory allocation
+* Select algorithms and data structures that are efficient and well-suited to the task, considering factors like computational complexity and memory usage. Use structs and data views for data organization and avoid unnecessary copying of data.
+* Use bitwise operations for efficient data manipulation, particularly when working with binary data or flags.
+* Use preprocessor directives for conditional compilation and code reuse.
