Summary
Previously grunt build would transpile the output of browserify to transpile all dependencies, but this would make some dependencies, such as core-js, unexpectedly transpiled. Also, this way of transpiling would create source maps only targeting the browserify output instead of original source, and makes the final
dist/exceljs.js
larger than expected.Test plan
Existing ci builds and manually tested in browser.
