[dba-VS] TypeScript

[Gustav Brock]

Hi Arthur et al

I managed to pass the course. It was a bit more difficult than expected because the instructors and the homework insist on a rigid use of interfaces even for the tiniest purpose - they call them baby interfaces -like:

    interface IArtStyle {
        name: string;
    }

Thus you get a tiny class like:

    class ArtStyle implements IArtStyle {
        name: string;
        constructor(artStyle: IArtStyle) {
            this.name = artStyle.name;
        }
    }

Effectively, as you can see, this holds nothing more than a string.
But it demonstrates the power of strong typing. 

Also the option for classes, inheritance, and modules (namespaces) really turns Javascript into a low-level language compared to TypeScript.

It took me many hours to create the final piece of code - until I found out that the provided JSON file was buggy. But, hey, isn't that real life? Never trust an unknown data source.

Gustav,

I too am taking the course. And thanks for the link to SublimeText. I just installed it on two physical boxes, running Windows 8.1 and Debian 14 on the other, plus one VM running Ubuntu. and VoltDB.

I haven't completed the course yet, but am sure liking what I've seen so far.
