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 following content does not reflect the final state of the ECMAScript 6 modules specification. For more accurate documentation, see ECMAScript 6 modules: the final syntax.

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.
