Demonstrating how to declare global variables is only half the job! The other half is accessing them which you failed to demonstrate!

ie: In the case of strings…

message:myGlobalVar;

message=myGlobalVar;

message=’myGlobalVar’;

message=”myGlobalVar”;

message= var.myGlobalVar;

Etc, etc… or should we come back next month for the second exciting episode of “Javascript… one bit at a time!”

Javascript, is crude and archaic enough without all these internet “teachers” wasting people’s time with drips and drabs!

If you’re gonna teach do it right or get off the airways so we can find someone who’ll CLOSE OFF a job!

Mats: Well I’m not particularly fond of Global variables since they are EVIL, but that’s a pretty interesting tool you’ve built. Some libraries really do clutter the global namespace.

Thanks for the link!

Yes, a lot of things has happened with Javascript the last few years. It has changed status from being considered a second grade language to proving to be really useful. I too think the js frameworks have helped making it more useful and popular.

The object model in Javascript is really cool. But it’s also widely misunderstood since it depends on prototypal inheritance which is not well understood by most people coming from languages with classical inheritance.

The more I learn about Javascript, the more I like it. No doubt it contains a lot of serious flaws, like global variables. But once your recognize them you can avoid them.

Yeap, objects are awesome. I think the JS frameworks are giving a new step to the language. OOP is being more and more present into a language that people underestimated for years in a row.

Like happened to C when became C with Classes (C++), is JavaScript evolving to JS++ ?
