6 Advanced JavaScript Techniques You Should Know - 3 views
-
-
Object-oriented JavaScript implements namespace-like principles due to the fact that properties and methods are declared inside of objects, thus there are less likely to be conflicts. A conflict could arise, however, through object names. And very likely, the conflict will occur "silently", thus you may not be alerted to the issue immediately.
-
if (typeof MY == "undefined") { MY = new Object(); MY.CUSTOM = new Object(); } MY.CUSTOM.namespace = function() { function showStatistics(args) { document.write("<p><strong>Name:</strong> " + args.name + "<br />"); document.write("<strong>Team:</strong> " + args.team + "<br />"); if (typeof args.position === "string") { document.write("<strong>Position:</strong> " + args.position + "<br />"); } if (typeof args.average === "number") { document.write("<strong>Average:</strong> " + args.average + "<br />"); } if (typeof args.homeruns === "number") { document.write("<strong>Home Runs:</strong> " + args.homeruns + "<br />"); } if (typeof args.rbi === "number") { document.write("<strong>Runs Batted In:</strong> " + args.rbi + "</p>"); } } showStatistics({ name: "Mark Teixeira", team: "New York Yankees", position: "1st Base", average: .284, homeruns: 32, rbi: 101 }); } MY.CUSTOM.namespace();

JavaScript: The World's Most Misunderstood Programming Language
-
This is misleading because JavaScript has more in common with functional languages like Lisp or Scheme than with C or Java.
-
It has arrays instead of lists and objects instead of property lists. Functions are first class. It has closures. You get lambdas without having to balance all those parens.
