JavaScript Comes of Age

I’ve been checking out the new Java SDK 8 with the Nashorn js engine and JavaFX. Very nice. Would love to see a good article on using it and bundling apps using it.

I think JS is going to become even more popular after ES6 comes in with its improvements. I read an interesting article on the tidal wave of frameworks though. Suggested that a more atomic style of using specific little libraries for specific things might be the future.

Interesting stuff.

ES7 is quite a way through the development process now so JavaScript should continue to evolve and become more and more powerful.

It’s a real pity that most college classes teach how to write JavaScript for Netscape 2-4 rather than any of the more modern versions.

Wow - that’s equivalent to learning how to ride a horse and cart instead of getting a drivers license.

A number frameworks and libraries - should be a number of…

Definitely. The other problem is that it will still be some time before we see this JS being used everywhere, what with slow browser upgrade adoption etc.

I like Javascript (or ECMAScript) very much. Thanks to that language’s object notation, we have a splendid lightweight data format named JSON.

There’s a bit about this in one of the later chapters in the book. I defnitely think the future will be all about small modules that do one thing very well, rather than huge monolithic frameworks that try to do everthing. This will definitely be easier when the module pattern from ES6 gets adopted.

You could even put lots of different modules together under an umbrella namespace using something like Ender or a build process, effectively creating your own custom bespoke framework.

This is such a shame. Most modern browsers have good support for the latest JavaScript and even quite a bit of ES6. You can also use various transpilers to use most of ES6 today, so it would be good to see courses teaching the most up to date methods so that people could see what JS is capable of!

Thanks - will try to get this changed!

I actually think that most modern browsers are updating quite quickly, so this isn’t as much of a problem as it used to be.

I love JSON! It hits the sweet spot between being a human and machine readable data format. And the fact that it can be encoded as a simple string makes it amazingly portable!

To start, this rand it not targeted to you personally. I like your article, it shows that JS is indeed a very mature language. One that has been around for a long while. Also comparing it to Java’s all platform mission is a +1! But…

Talking about Object Oriented programming vs Functional programming in JS is simply not understanding JS.

To be honest, I’m sick and tired of all those ‘write OO in JS’-tutorials. They make for bad code, var self=this; crap and people panicking when this suddenly is not this but that, or window.
As long as people write articles about JS Objects and how to write ‘OO’ code in JS, it will stay in puberty.

Also, stop calling it asynchronous. It simply isn’t. JavaScript is a blocking synchronous language. The only asynchronous thing in JavaScript are certain browser api’s. for instance the XHR object, a good answer can be found here: http://stackoverflow.com/a/2035662/2496717

You also state ‘Closure’ as being a cool feature of the language. Not sure you understand what a Closure is, nearly all languages have them, not so special imo.

And your last statement about learning JS as a first programming language. Couldn’t agree less. Javascript is a very hard language to grasp. Just try and explain what ‘this’ is: http://bjorn.tipling.com/all-this or perfectionkills(dot)com/know-thy-reference/ . Add the hard to grasp prototyping + new key word, and you have yourself a very powerfull but hard to learn language.

A small snippet to end: typeof new String(‘foo’) != typeof ‘foo’ && new String(‘foo’) == ‘foo’. I rest my case, hard to learn

Hi pinoniq,

Thanks for your feedback - it’s always good to see the other side of things, and the links you sent made interesting reading.

I think that JS struggles with both an OO and functional approach, but the fact is that you can do both in JS, if you want to. I’d be interested to hear why you think the OO approach is so bad?

Yes I agree that the language itself isn’t asynchronous, but the way callbacks (and promises) are used makes the language behave as if it was asynchronous.

I still stand by my assertion that JS is a good language to learn for a first timer. I think the advantage is that people can learn JS using just their browser and it also gives them access to lots of other places to practice and see examples. Yes it has more quirks than most languages, but don’t all languages have some difficult ideas to get your head around? I think you can get the basics of programming without running into too many JS gotchas.

Cheers,

DAZ

i love javascript from server side to client side :slight_smile: :smile: gonna rock !

The fact that Javascript is being used for programming hardware now is an indication of it’s maturity. On a lighter note, emulation of older computers for games is far better now. Here are some examples:

No more having to faff about with software such as DOSbox, just play in browser. After years of hating the language, I love it for the above sites alone! :slight_smile:

I’ve just been reliving some childhood memories playing Chuckie Egg!

Yes I agree, that JavaScript’s quirks and annoyances are outweighed by its ubiquity in the browser nowaday. And more and more applications are showing what it is capable of!

Chuckie Egg!!!
That is a blast from the past!
How many hours did I spend on that game?

I spent many childhood hours playing this - the shock when the giant bird started chasing you!
