Consistent locale definition pattern using H5.merge() to extend CultureInfo with numberFormat, dateTimeFormat, and TextInfo objects. All locale files follow identical structure, enabling reliable globalization in generated JavaScript applications. This pattern demonstrates skill in creating maintainable, standardized internationalization data that could be extracted for use in other .NET-to-JavaScript tools.

Thread-local StringBuilder implementation that caches instances per thread to reduce allocations. The component is self-contained, requires only System.Threading, and demonstrates non-obvious skill in high-frequency string manipulation optimization. Could be reused in any performance-sensitive .NET application with minimal modification.

Tracks type dependencies during the translation process to determine what needs to be included in output. Implements a clean resolver pattern that could be adapted for other code analysis or transformation tasks. Shows skill in managing complex translation dependencies without tight coupling to the rest of the translator.
