Comparing the performance of finding the most significant digit (in base 10), utilizing string interpolation and also log().

Which is faster to check if function has not been passed too many arguments?

Testing a linked list queue vs a double list queue for different performance scenarios.

In FF if the object being iterated over is large enough it will trigger an expensive cycle collection with Test #1. Test #2 runs approximately 100 times faster on FF. The difference is marginal in Chrome. To see the difference in timing, I recommend loading up the debugger console to see exactly how many ms each run takes.

Testing the cheapest pattern for filtering an array of objects based on attribute.
