Can you provide a browserify distribution?

[hoogw]

I have tried browserify, but run into error as
can you provide a browser version of it?

                        browserify index.js --s rbush -o dist/rbush.js  

                        /Users/nicole/node/rbush/index.js:1
                       import quickselect from 'quickselect';
                      ^
                       ParseError: 'import' and 'export' may appear only with 'sourceType: module'

There's already a browser version distributed, e.g. https://unpkg.com/rbush@3.0.1/rbush.js
