I am using IE11 for dev, if I build, it has SCRIPT 1002 error.
Chrome or edge is okay, so I think it seems js(es6) support issue.
The handsontable and dependencies versions and code, error images are below.
Can you please share the exact browser version and system?
Also, I wanted to confirm if you used CLI react-create-app to construct the example or you’ve used some custom setting.
