    export

    This is a new technology, part of the ECMAScript 2015 (ES6) standard .
    This technology's specification has been finalized, but check the compatibility table for usage and implementation status in various browsers.

    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). A new export declaration is specified by ECMAScript 2015 modules.

    Syntax

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

    Description

    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.

    Specifications

    Prior to ECMAScript 2015, no import/export or module functionality has been defined in ECMA-262 standards.
