    ParallelArray Redirect 1

    This content covers features introduced in Firefox 17

    Obsolete since Gecko 29 (Firefox 29 / Thunderbird 29 / SeaMonkey 2.26)
    This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Note: As of Gecko 22, this object is disabled in the Beta, Release and ESR channels (bug 853067). This object has been removed from Gecko 29 in favor of ParallelJS (PJS) currently available in the Nightly channel (bug 944074).

    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)

    ParallelArray instances

    Properties

    length
    Reflects the number of elements in the ParallelArray.

    Methods

    map
    Apply map callback to array elements.
    reduce
     
    scan
    scatter
    Scatter array elements.
    filter
    flatten
    partition
    get
    Get ParallelArray element.

    Examples

    Example: Using map in parallel

    var p = new ParallelArray([0, 1, 2, 3, 4]);
    var m = p.map(function (v) {
      return v + 1;
    });
