Array^(native)

Represents indexed vector (array) of values. The Array object is used to store multiple values in a single variable.

Example

// An array can be defined in three ways. // 1. var myCars=new Array(); myCars[0]="Saab"; myCars[1]="Volvo"; myCars[2]="BMW"; // 2. var myCars=new Array("Saab", "Volvo", "BMW"); // condensed array // 3. var myCars=["Saab", "Volvo", "BMW"]; // literal array

Properties

• [begin..end] : Object
  Returns part of vector and contains elements from beginning index and up to or excluded end index. Begin or/and end are optional. If begin is ommited then it is assumed to be 0, if end - length is used as end value.
• [index] : Object
  Refers to a particular element of the array at the index position. Index is zero-based.
• length : Integer
  GetNext number of items in array

Methods

• clone() : Array
  Returns brand new copy of the array.
• concat([value1 [, value2 [, ... valueN]]]) : Array
  Appends array by values.
• filter(callback[, thisObject]) : Array
  This method calls the callback function once for each element in the array, and constructs new array of all the values for which the callback returns true. The filter method does not mutate the array on which it is called.
• indexOf(value [,notfound = -1]) : Object
  Find value in the array.
• join(delimiter) : String
  Creates string fram all array's elements separated by the delimeter. If delimiter is not specified, the default is comma.
• lastIndexOf(value [,notfound = -1]) : Object
  Get last index of the value in array. If the value is not found returns the notfound value (-1 by default).
• map(callback[, thisObject]) : Array
  This method creates a new array with the result of calling a provided callback function on every element in this array. If thisObject is provided then the callback will have it as this. The map method does not mutate the array on which it is called.
• pop() : Object
  Removes last element from array. This affects the length of the array!
• push([value1 [, value2 [, ... valueN]]]) : Object
  
• reduce(callback[, initialValue]) : Array
  This method applies the function simultaneously against two values of the array (from left-to-right) as to reduce it to a single value. The method returns result of last callback invocation. The method does not mutate the array on which it is called.
• remove(index) : Object
  Removes element at index.
• removeByValue(value) : Object
  Tries to locate element by value in the array and removes it.
• reverse() : Array
  Reverses order of elements in the array in-place. Returns the array.
• shift() : Object
  Removes first element of the array. This method changes the length of an array!
• slice(start [, end]) : Array
  Create new array consisting from elements of the array from start up to but not including end index, order between start and end (not included) index.
• sort([sortFunction]) : Array
  Sorts elements of the array in ascending order, if the sortFunction provided is used for comparing elements during sort.
• this(..) : Array
  Creates new array object from arguments provided.
• toString() : String
  Create comma separated string from array.
• unshift(value) : Object
  Inserts a value at first array position.
• valueOf() : String
  Same as toString - creates comma separated string from array.
