    The export statement is used to allow a signed script to provide properties, functions, and objects to other signed or unsigned scripts. It is an ancient Netscape 4 feature that has been removed in Firefox 3.5 (bug 447713). In the future, a new export declaration will be specified by ECMAScript 6 modules.


    Example 1:
    export name1, name2, ..., nameN;
    Example 2:
    export *; 
    Property, function, or object to be exported.


    Typically, information in a signed script is available only to scripts signed by the same principals. By exporting properties, functions, or objects, a signed script makes this information available to any script (signed or unsigned). The receiving script uses the companion import statement to access the information.

    Example 1 shows the syntax for exporting specified properties, functions, and objects.

    Example 2 shows the syntax for exporting all the properties, functions, and objects from the script.


    Prior to ECMAScript Edition 6, no import/export or module functionality has been defined in ECMA-262 standards.
