Simply open index.html with Firefox, Safari or IE11+, and enter some content.
Values starting with = are parsed as formula written in JavaScript, for example =A1*C1.
If you'd like to use Chrome, type make run or node extra/static-here.js and connect to localhost:8888 to view the demo.
To build from source, first install NodeJS 0.10 or later, and run make (only tested on Linux/OSX at the moment).
JS source code (main.js and worker.js) are written in ECMAScript 6 (aka ES.next, aka Harmony), specifically the subset marked with TC39 Consensus as of February 2014.
For backward compatibility with ECMAScript 5 browsers, we use Traceur to compile source files into the es5/ directory.
If you prefer to work directly with the 2010 edition of JS, the as-javascript-1.8.5 directory has main.js and worker.js written in the style of ES5; the source code is line-by-line comparable to the ES6 version with the same line count.
For people preferring a cleaner syntax, the as-livescript-1.2.0 directory uses LiveScript instead of ES6 to write main.ls and worker.ls; the source code is 20 lines shorter than the JS version.
Building on the LiveScript language, the as-react-livescript directory uses the ReactJS framework; the source code is 10 lines more than the AngularJS equivalent, but runs considerably faster.
For the version without AngularJS version, using only basic ES5 and raw DOM APIs, the source code still clocks at 99 lines, albeit with some short statements joined together.
