03 / ORIGINAL ISSUE TEXT

chaijs/chai #1687 · read the original issue

The bundled lib (see `chai/chai.js` on [npm](https://www.npmjs.com/package/chai?activeTab=code), L156-158) uses static initialization blocks that are only supported in newer browser versions: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/Static_initialization_blocks .

This breaks support for Safari 14 and 15, which are supposed to be supported according to the release notes on v5: https://github.com/chaijs/chai/discussions/1565 .

Changing the esbuild target to e.g. 'es2021' should fix this problem 🙂
