As of 2026-08-26 (commit e95d9dbbec2a), jestjs/jest contains 140,017 total lines: 72,097 code, 43,834 comments, 24,086 blank, across 1,645 files in 15 languages (top: TypeScript 78.0%). Counted with tokei via OctoCounts.
OctoCounts produced this report by resolving jestjs/jest to commit e95d9dbbec2a, downloading the repository source archive, and counting every source file with tokei, the open-source line counter written in Rust. The table below breaks the count down by programming language into files, total lines, code lines, comment lines, and blank lines, so the figures can be compared across languages and projects. Results are cached by commit, tokei version, and analysis options, so counting the same revision again reproduces exactly these numbers.
This is a medium-sized codebase by counted code lines. Code represents 51.5% of all lines, comments represent 31.3%, and the repository averages 44 code lines per file. TypeScript accounts for 78.0% of counted code.
