Push the JS engine to its limit: standalone bundles + ~25 helper methods.

gridlang js-bundle — package a .grid file's data + compute layer into a single self-contained .js file:

gridlang js-bundle report.grid -o bundle.js     # Node bundle
gridlang js-bundle report.grid --browser ...    # Web Worker bundle
node bundle.js                                  # prints JSON

Expanded df API (8 → 25 methods):

  • Aggregations: count, variance, std, median, quantile, describe
  • Filtering: head, tail, slice, distinct, find, some, every, none
  • Sorting: sortBy({desc?}), groupBy, countBy
  • Reshaping: pluck, drop, rename, assign
  • Joins: join, leftJoin, concat
  • Conversion: toRecords, toCSV
  • Metadata: columns, shape, empty

All chainable — df.where(p).sortBy(c, {desc:true}).head(3).col("x").

JS source extraction — gridlang/js/{df_helpers,bridge_node,runtime_pipeline}.js are now plain files (no inline Python strings); shared by the in-process bridge and bundles.

378 tests. See spec/SPEC.md §20.
