The best sessions here at QCon London<\/a> have been the small ones, not the big ones. Yesterday the slot I enjoyed most was from Attila Szegedi on JavaScript in the Enterprise. He uses Mozilla Rhino<\/a> for server-side development. It\u2019s not a mainstream choice; but he made a case for it, saying that continuations<\/a> in JavaScript bring huge benefits, that there is a ready supply of developers with JavaScript skills (albeit mostly browser-based), and JavaScript is so flexible that he can work around any limitations.<\/p>\n

One example is that JavaScript has no namespaces; but it does support function pointers, so he adds a bunch of function pointers as members of an object, and then that object works like a namespace.<\/p>\n

Szegedi says he has little interest in ECMAScript 4.0 \u2013 once thought to be the future of JavaScript \u2013 because there is no community consensus around it.<\/p>\n

Today I\u2019ve just attended a session on Microsoft F#<\/a> given by Amanda Laucher. F# is a functional language that will be released as part of Visual Studio 2010. I knew little about it until today. Laucher gave a code-heavy presentation looking at how the ease of concurrency in F# can greatly increase speed of execution, using an example from the car insurance industry.<\/p>\n

Laucher said that threading in C# is horrible in comparison.<\/p>\n

Developers are not going to abandon C# or Visual Basic in favour of F#. Rather, they will encapsulate pieces of functionality in F# where they can get benefit, and call them from their C# or VB application.<\/p>\n
