Functional Programming with Arrays

Leave a comment

As object oriented programming starts to fall out of favor with developers, functional programming is making a comeback. Reasons such as side effects and unit testability are hastening it. The Telerik developer blog has a great post up detailing functional programming with arrays.

They have examples of map, filter, and of the lesser known reduce. There is even a pretty easy to understand example of currying in javascript. All in all, if you are new to javascript or coming up to the newer syntax, this post is a great teaching tool. And honestly it is also a great reference to keep when you have that mid-day coding session brain fart.

VS Code Text Buffer Reimplementation

Leave a comment

The VS Code team has a really good article around their Text Buffer Reimplementation in the latest version. There is a lot of good information around performance and the implications of certain design patters revolving around file size.

Piece Tree Performance
Piece tree performance with a large file and multiple edits.

The part that is very interesting is how the piece tree seemed to be the clear cut winner. It wasn’t until they tested a large file with a large amount of edits, that it stumbled more than the array. Articles like this fascinate me when Javascript is pushed to its limits.
