Unstandard Library for JavaScript

Have you ever written code that you used in more than one project? Me too.

This is a compilation of highly-reusable code for JavaScript.

See also: unstdlib.py for Python.

Highlights

Some cool noteworthy code in this library:

• iter_line(A, B, fn) in src/geometry.js implements Bresenham's line algorithm.
• cycle(a) in src/core.js implements Python's itertools.cycle(iterable).
• counter_callback(count, callback) in src/core.js implements a really handy for executing a function on completion of a bunch of asynchronous calls.
• src/binarysearch.js contains optimized implementations of various binary search related functions.

Organization & Philosophy

At the time of writing this, there is no organization or philosophy for this library. It's a bunch of code I wrote on various projects like LineRage (a fast-paced canvas-based game that required a lot of fun optimizations). Some of the code is optimized excessively in interesting ways, whereas other parts are just convenience helpers.

The spirit of the code within is to ignore error checking in favour of elegance and performance. Unexpected input will result in unexpected behaviour.

TODO: Rewrite this section once the code has been organized.

TODO

• Enclose functions in an unstdlib namespace.
• Write docstrings for all functions.
• Write unit tests.

Contributors

Forks are highly encouraged. Everyone should have a collection of code they commonly reuse. If you feel your code will be useful to others, make sure that it is conforming to the spirit of the library outlined in the Organization & Philosophy section and send over a pull request.
