There's a debate to be had about whether using JavaScript or TypeScript leads to better outcomes when building a project. The introduction of using JSDoc annotations to type a JavaScript codebase introduces a new dynamic to this discussion. This post will investigate what that looks like, and come to an (opinionated) conclusion.
I was recently reading a post by Jaime González García which featured the following mind-bending proposition:
I previously attempted to migrate my Jasmine tests from JavaScript to TypeScript. The last time I tried it didn't go so well and I bailed. Thank the Lord for source control. But feeling I shouldn't be deterred I decided to have another crack at it.
I wrote a little while ago about creating a directive to present server errors on the screen in an Angular application. In my own (not so humble opinion), it was really quite nice. I was particularly proud of my usage of isolate scope. However, pride comes before a fall.
The modern web is JavaScript. There's no two ways about it. HTML 5 has new CSS, new HTML but the most important aspect of it from an application development point of view is JavaScript. It's the engine. Without it HTML 5 wouldn't be the exciting application platform that it is. Half the posts on Hacker News would vanish.
OK the title of this post is a little verbose. I've just wasted a morning of my life trying to discover what happened to my ability to debug JavaScript in Visual Studio 2012. If you don't want to experience the same pain then read on...
I have occasionally done some server-side JavaScript with Rhino and Node.js but this is the exception rather than the rule. Like most folk at the moment, almost all the JavaScript I write is in a web context.
I wanted to write about a JavaScript library which seems to have had very little attention so far. And that surprises me as it's
I've so named this blog post because it shamelessly borrows from the fine work of others: Sebastian Markbåge and Nathan Vonnahme. Sebastian wrote a blog post documenting a good solution to the ASP.NET JavaScriptSerializer DateTime problem at the tail end of last year. However, his solution didn't get me 100% of the way there when I tried to use it because of a need to support IE 8 which lead me to use Nathan Vonnahme's ISO 8601 JavaScript Date parser. I thought it was worth documenting this, hence this post, but just so I'm clear; the hard work here was done by Sebastian Markbåge and Nathan Vonnahme and not me. Consider me just a curator in this case. The original blog posts that I am drawing upon can be found here: 1. http://blog.calyptus.eu/seb/2011/12/custom-datetime-json-serialization/ and here: 2. http://n8v.enteuxis.org/2010/12/parsing-iso-8601-dates-in-javascript/
Yes the title of this post is *painfully* verbose. Sorry about that. Couple of questions for you: - Have you ever liked the way you can have base classes in C# which can then be inherited and subclassed in a different file / class
So it's 2010 and I've started using jQuery. jQuery is a JavaScript library. This means that I'm writing JavaScript... Gulp! I should say that at this point in time I *hated* JavaScript (I have mentioned this previously). But what I know now is that I barely understood the language at all. All the JavaScript I knew was the result of copying and pasting after I'd hit "view source". I don't feel too bad about this - not because my ignorance was laudable but because I certainly wasn't alone in this. It seems that up until recently hardly anyone knew anything about JavaScript. It puzzles me now that I thought this was okay. I suppose like many people I didn't think JavaScript was capable of much and hence felt time spent researching it would be wasted. Just to illustrate where I was then, here is 2009 John's idea of some pretty "advanced" JavaScript:
