YUI Theater: Douglas Crockford, The JavaScript Programming Language

January 24, 2007 at 3:39 pm by Eric Miraglia | In Development, YUI Theater | 42 Comments

I’ve shared on YUIBlog and in the YUI Theater two presentations created by Yahoo! JavaScript Architect Douglas Crockford (“Advanced JavaScript” and“An Inconvenient API: The Theory of the Dom”). Today I’m happy to announce that Douglas’s more foundational talk “The JavaScript Programming Language,” is publicly available on Yahoo! Video. In this presentation, which is meant to be the beginning of the three-course sequence (followed by “Theory of the DOM” and then “Advanced JavaScript”), Douglas explores not only the language as it is today but also how the language came to be the way it is.

It’s always worth pointing out that ideas and perspectives are Douglas’s own and that the many eggregious flaws in videographic craftsmanship are mine. Files are available from Yahoo! Video (Flash) or as iPod-compatible .m4v files.

If you’re viewing this in a flash-capable viewer, you can check out Part One in the embedded player below:

Als Format wurde das iPod-Format “.m4v” gewählt, das mein freundlicher Betrachter VLC zum Glück klaglos abspielt. Vorsicht, die Dateien sind seeeehr fett. Ich habe die Videos noch nicht gesehen, denke aber, daß sie einen Blick lohnen. Hoffentlich wandelt Yahoo fortan auch die anderen ihrer bislang nur durch den Yahoo-Player anschaubaren Videos um.

I’ve been programming in Javascript for a very long time and I’d like to think that I’m pretty good at it. I still managed to learn a lot from this series. I really like Doug’s style. So when are we going to get to see the “Advanced” lessons that he mentioned all through his class?

[...] Yahoo! is making a few classes on Javascript available through their YUI Theater blog. The classes are given by Douglas Crockford, who is Yahoo!’s Javascript Architect. I took sometime this evening to go through the “Javascript Programming Language” presentation and learned a great deal about the language, which is going to be directly applicable to the work that I am currently doing at TransZap. I would recommend this presentation to anyone who is going to do extensive work using Javascript, which is essentially anyone doing Ajax or Web 2.0 work. [...]

Thanks,

[...] Strongly Typed Because my job is changing, I’ve been spending some time learning some other languages since I’ve been focused on Java and XML tools for the last few years. So, I’m refreshing my skills in C++ and PERL and trying out JavaScript and LSL. All my Java programming has been done in Eclipse which does a wonderful job of flagging errors as you type. That is, the development cycle of “write, compile, fix compile errors, compile, …, run” because if Eclipse doesn’t show any errors while you’re typing, it’s sure to compile. So, what does this have to do with C++, JavaScript and most of the XML tools? After Java and Eclipse, I feel like I’m being thrown back 20 years to using Lint with my C programs. And this leads me to the topic of ’strongly typed’ languages. One of features of Java is it’s ’strong typing’. I don’t care about the JVM runtime checking (since code has to be robust and recover from all errors, the overhead of checking rather than just doing and faulting is questionable) but I care about the compiler and, in this case, the editor knowing what I want to happen — if I say itemCount is a string but then I add one to it something should be flagged; if I define a variable named height and then reference a variable named heigth something should ask me what I was thinking. This feature of the programmer defining something and then the compiler or editor being able to check the implications of that definition. But, now it is 2007, and Douglas Crockford (in his excellent JavaScript video lectures) recommends style conventions which allow running JSLint to save yourself from wasting time finding problems at runtime. Well, duh. He does mention that this capability is being added to the Eclipse JavaScript plugin, but, after all these years of computer science, couldn’t anyone see the language had problems? I have the same arguement with PERL and most of the XML languages (a typo in an XPath expression silently select nothing with know why to debug why, for instance). CSS is hard to get right on web pages because there is no check if the HTML being styled fits the formatting model that the CSS operates on. C++ lets you override methods in subclasses with no checking for the matching semantics. PERL, well, don’t get me started on PERL. My frustration is that, after 40 years of computer language design, this still isn’t obvious. Any language design should have a non-onerious method for the programmer to state his or her intentions and those intentions can be verified before you actually try executing the bits. Our focus should be on finding light-weight methods for expression of complex intentions not in making the latest light-weight language that has the problems of it’s predecessors. [...]

Excellent tutorial!

A minor question: in Part 2, there is a slide saying “objects are passed by reference..not passed by value”.

I guess javascript and java follow the similar behavior in function argument passing. But explicitly in Java spec, “arguments are passed by value”.

Although most developers know the behavior, the terms being used in different context are still confusing.

I can’t view any of the JavaScript videos. All I see is a black screen. Please advose

Comment by Rechell Schwartz — May 2, 2008 #
Rechell — I don’t have great advice for you. The .m4v files might work better on some systems if you rename them .mp4; trying to view them in iTunes may also work (iTunes loves m4v). The Yahoo Video pages have worked on all Flash-enabled systems on which I’ve used them. Sorry for the troubles you’re having. Regards, Eric
