Summary
The goal of ParallelArray is to enable data-parallelism in web applications. The higher-order functions available on ParallelArray attempt to execute in parallel, though they may fall back to sequential execution if necessary. To ensure that your code executes in parallel, it is suggested that the functions should be limited to the parallelizable subset of JS that Firefox supports.
Syntax
new ParallelArray() new ParallelArray([element0, element1, ...]) new ParallelArray(arrayLength, elementalFunction)
