ClassicASP.JS.Packer

This is Dean Edwards /packer/ (a JavaScript compressor) written in JScript and compatible with VBScript in Classic ASP.

JScript is Microsoft's legacy dialect of the ECMAScript standard; it should not be confused with JavaScript. JScript can run server-side in .asp pages and is compatible with .asp pages written in VBScript. JScript is similar to JavaScript, but much more limited. As a result, this version of Dean Edwards /packer/ is v1.1 (the latest and final version is 3.0).

Not only is this is a very useful JavaScript compressor, it's also a great JavaScript obfuscator, meaning it can take JavaScript code and make it very difficult to read. This can help protect against data scraping. For example, if you've paid for geographical data and wish to implement it in a project such as OpenStreetMap, you need to use JavaScript, but ideally you don't want the raw data easily readable in the source code.

Below I will demonstrate this with an OpenStreetMap example that uses longitude/latitude data to pin museums in Manhattan.

OpenStreetMap Example

First, let's look at the uncompressed JavaScript output.

NOTE: I'm using a 2D array for demonstration purposes as appose to retrieving data from a database backend.
