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.
- Simple actions (JavaScript)
  A simple action performs a pre-programmed activity that can be modified by arguments.
- Global objects and functions (JavaScript™)
  Global objects provide entry points to server-side scripts. Entering the name of a global object instantiates it.
- DOM (JavaScript)
  Represents a document in XML Document Object Model format.
- Domino®
  This library provides access to the HCL Domino® back-end.
- Runtime (JavaScript)
  The Runtime library contains classes that provide useful methods for globalization.
- Standard (JavaScript)
  The Standard library contains classes for manipulating data of different types and performing common operations.
  - Array (Standard - JavaScript)
    Represents an array.
    - Array (Array - JavaScript)
      Creates a new Array object.
    - concat (Array - JavaScript)
      Constructs a new array from an array plus appended elements.
    - join (JavaScript)
      Joins the elements of an array to form one string.
    - pop (JavaScript)
      Removes the last element of an array.
    - prototype (Array - JavaScript)
      Extends the object with additional properties and methods.
    - push (JavaScript)
      Appends elements to an array.
    - reverse (JavaScript)
      Reverses the order of the elements of an array.
    - shift (JavaScript)
      Removes the first element of an array.
    - slice (Array - JavaScript)
      Gets elements from an array to form another array.
    - sort (JavaScript)
      Sorts the elements of an array.
    - splice (JavaScript)
      Deletes elements from an array, optionally replacing them, to form another array.
    - toLocaleString (Array - JavaScript)
      Gets the string representation of an Array object taking into account the host locale.
    - toString (Array - JavaScript)
      Gets the string representation of an Array object.
    - unshift (JavaScript)
      Prefixes elements to an array.
  - Boolean (Standard - JavaScript)
    Represents a boolean value.
  - Date (Standard - JavaScript)
    Represents a date and time.
  - Math (JavaScript)
    Represents common mathematical values and functions.
