Code Analysis

6 files read · 2 rounds

A monorepo containing four React demos that showcase pure-JavaScript implementations of Parquet parsing (Hyparquet), Iceberg reading (Icebird), SQL streaming (Squirreling), and virtualized tables (HighTable).

Strengths

The code demonstrates deep algorithmic substance in parsing binary formats without native bindings, particularly in the `ParquetGrid` visualization and `parquetDataSource` streaming logic. The architecture is clean with a clear separation between demo applications and core library utilities.

Weaknesses

Test coverage is minimal (only basic type checks), and there is some boilerplate repetition across the four demo apps which slightly reduces modularity.
