Implements Base64 Variable-Length Quantity (VLQ) encoding and decoding, a fundamental algorithm for source map generation. The code is self-contained, handles signed integers, and uses bitwise operations cleanly. It can be extracted and reused in any project needing VLQ encoding (e.g., custom source map generators, data serialization). Demonstrates non-obvious skill in bit manipulation and compact encoding.

Provides dependency graph construction, topological sorting, and module assignment for code splitting. The algorithms (topo-sort, deepest-common-parent, expand-modules) are generic and well-implemented with clear separation of concerns. This module could be extracted and reused in any build system or dependency resolver that needs to order modules and detect cycles. It demonstrates solid data structure and algorithm design.

Parses JavaScript files to extract goog.provide and goog.require declarations, builds a dependency index, and computes dependency order for Google Closure Library-style JS. The code handles scanning classpath/jar resources, parsing JS with regex, and building a dependency graph. This is a reusable utility for any project that needs to analyze Closure-style JS dependencies or build a similar index for other JS module systems.

A full port of Clojure's clojure.pprint to ClojureScript, implementing Common Lisp's format function (cl-format) with directives for tabular, cardinal, ordinal, roman numerals, etc. It uses protocols for custom writers, multimethods for dispatch, and a token-buffer approach for line breaking. This is a large, self-contained library that can be extracted and used in any ClojureScript project needing advanced formatting or pretty-printing. Demonstrates deep understanding of formatting algorithms and Lisp traditions.
