Douglas Crockford, author of JavaScript: The Good parts, recently gave a talk called The Better Parts, where he demonstrates how he creates objects in JavaScript nowadays. He doesn't call his approach anything, but I will refer to it as Crockford Classless.
Crockford Classless is completely free of class, new, this, prototype and even Crockfords own invention Object.create.
I think it's really, really sleek, and this is what it looks like:
function dog(spec) {
| // Method 1: simply use Highcharts built-in functionality (SVG -> Highcharts server -> PNG) | |
| // Downside: won't work in webview native apps that don't handle the form response | |
| highcharts.exportChart({ | |
| filename: filename | |
| }); |
| // a list of useful queries for profiler analysis. Starting with the most basic. | |
| // 2.4 compatible | |
