Title: Optimization to shallow flatten

When we are doing shallow flattening, using

Array.prototype.concat.apply([], array);

is faster (see http://jsperf.com/fastest-way-to-merge-2-dimension-arrays)

The length <= 10000 is because there is a limit to the number of
parameters passed to a function.

P.S.: I should probably have included lodash with no conflict, if it's a problem I can change that and run them again.
