Dean Edward’s packer: A JavaScript compressor

If you’re using JavaScript, you might consider using packer before deploying your code. It will compress your JavaScript code and in most cases will make your code smaller. When you use the compressed JavaScript online, it will result in bandwidth savings.
The method is simple, copy your code on the Paste text box, select whether you want to use Base62 encode and Shrink variables option, and click the Pack button. The documentation says that you must terminate statements, including function declarations, with semicolon so you better abide it.
