JavaScript and XPages reference
This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions.
JavaScript™ language elements (JavaScript™)
The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see http://www.ecma-international.org/publications/standards/Ecma-262.htm). The JavaScript described here applies to the server-side interpreter. Client-side scripts are interpreted by the browser.
Statements (JavaScript)
JavaScript™ statements consist of keywords and syntax.

Statements (JavaScript)

JavaScript™ statements consist of keywords and syntax.

A single statement may span multiple lines.
Multiple statements may occur on one line separated by semicolons.
A semicolon may optionally terminate the last statement on a line.

See the ECMA specification (http://www.ecma-international.org/publications/standards/Ecma-262.htm) for a description of the statements. Note the following exceptions:

import (implementation-specific) is supported to import code from a script library. See import (JavaScript).
export (implementation-specific and not in the ECMA standard) is not supported.
label (not considered good programming) is not supported.
