An array is used to store multiple values in a single variable. Example array: the example given above shows an array with 4 elements (values), the elements are "strings". Each element is seporated by commas: "," Arrays are indexed from 0, meaning the first elements index is 0, the second elements is 1 and so on. An array element can be referenced separately, like so: The above example will return "Safari" as safari has an index of 0 within the "browser" Array.

The following functions can be used to manipulate an array. Click each function name in the table below for more details of it, with examples. Function Type Description push int Adds one or more elements to the end of an array and returns the new length of the array. pop string Removes the last element from an array and returns the value of that element. unshift int Adds one or more elements to the beginning of an array and returns the new length of the array. The other elements in the array are moved from their original position, i, to i+1. shift int Removes the first element from an array and returns that element. The remaining array elements are moved from their original position, i, to i-1. concat array Used to join two or more arrays together. sort array Used to sort the order of array elements. join string Takes an array and joins the elements into one string. IndexOf int Checks for the first instance of an element and returns its position. lastIndexOf int Checks for the last instance of an element and returns its position. reverse array Reverses the order of the elements in the array. splice array Add or remove elements to or from an array, and return the removed elements. slice array Returns the selected elements in an array, as a new array object. length int Returns the length of an array. substr String This is used to return a section of a string

Name Type Description Multi Dimensional array Allows multiple arrays within a single array. Array Collections array An array consisting of JSON objects.

Usage: array.push("x") Adds one or more elements to the end of an array and returns the new length of the array. Example: myArray = ["a","b","c","d"] echo "myArray = "+myArray returnVal = myArray.push("e") echo "myArray = "+myArray echo "returnVal = "+returnVal Result: myArray = a,b,c,d myArray = a,b,c,d,e returnVal = 5

Usage: array.pop() Removes the last element from an array and returns the value of that element. Example: myArray = ["a","b","c","d"] echo "myArray = "+myArray returnVal = myArray.pop() echo "myArray = "+myArray echo "returnVal = "+returnVal Result: myArray = a,b,c,d myArray = a,b,c returnVal = d

Usage: array.unshift("x") Adds one or more elements to the beginning of an array and returns the new length of the array. The other elements in the array are moved from their original position, i, to i+1. Example: myArray = ["a","b","c","d"] echo "myArray = "+myArray returnVal = myArray.unshift("_") echo "myArray = "+myArray echo "returnVal = "+returnVal Result: a,b,c,d _,a,b,c,d 5

Usage: array.shift() Removes the first element from an array and returns that element. The remaining array elements are moved from their original position, i, to i-1. Example: myArray = ["a","b","c","d"] echo "myArray = "+myArray returnVal = myArray.shift() echo "myArray = "+myArray echo "returnVal = "+returnVal Result: myArray = a,b,c,d myArray = b,c,d returnVal = a

Usage: array.concat() used to join two or more arrays together.

boy = ["Luke", "Bob","Jason"] girl = ["Emma", "Katie", "Chiara"] uni = ["Jordan","alex","Jessie"] names = uni.concat(girl,boy) echo names

Jordan,alex,Jessie,Emma,Katie,Chiara,Luke,Bob,Jason

Usage: array.sort() Used to sort the order of array elements. Example: array = ["b", "a", "d", "c"] echo array.sort() Result: a,b,c,d

Usage: array.join() Takes an array and joins the elements into one string. Example: array = ["a", "b", "c", "d"] echo array.join() Result: "a,b,c,d"

Usage: array.indexOf() Checks for the first instance of an element and returns its position. If the item is not found, it will return as "-1" If the item is present more than once, the indexOf method returns the position of the first occurrence. Example: array = ["google", "yahoo", "DuckDuckGo", "Bing"] echo array.indexOf("DuckDuckGo") Result: 2

Usage: array.lastIndexOf() Checks for the last instance of an element and returns its position. If the item is not found, it will return as "-1" If the item is present more than once, the lastIndexOf method returns the position of the last occurrence. Example: array = ["google", "yahoo", "DuckDuckGo", "Bing","DuckDuckGo","google"] echo array.lastIndexOf("DuckDuckGo") Result: 4

Usage: array.reverse() Reverses the order of the elements in the array. Example: count = ["1","2","3","4","5"] echo count.reverse() Result: 5,4,3,2,1

Usage: array.splice() adds or removes elements to or from an array, and returns the removed elements. Example: browser = ["Safari", "IE", "FireFox", "Chrome"] echo browser.splice(2, 2) Result: FireFox,chrome Safari,IE

Usage: array.slice() The slice() method returns the selected elements in an array, as a new array object. The slice() method selects the elements starting at the given start argument, and ends at, but does not include, the given end argument. Example: browsers = ["IE", "Chrome", "FireFox", "Safari", "SeaMonkey"] Good = browsers.slice(1, 3) Result: Good = Chrome,FireFox

Usage: array.length Returns the length of an array as an integer. Example: array = SearchEnemyCastles(10) echo "length: " + array.length + ", id: " + array[0].id + ", CityName: " + array[0].name + ", userName: " + array[0].userName + ", alliance: " + array[0].allianceName + ", prestige: " + array[0].prestige + ", honor: " + array[0].honor Result: length: 19, id: 17894, CityName: RED, userName: SomeN00b, alliance: 422, prestige: 6758, honor: 10495584936

Usage: array = [1,["a1","a2","a3"],["b1","b2","b3"],2] Example: array = ["bob",["count",1,2,3],["letters","a","b","c"],"bill"] echo array[1][0]+" The amount of "+array[2][0]"in this array." echo array[1][1]+". "+array[1][1] echo array[1][2]+". "+array[1][2] echo array[1][3]+". "+array[1][3] echo array[0]+" & "+array[3]+" have been added to the main array also." Result: - count The amount of letters in this array. - 1. a - 2. b - 3. c - bob & bill have been added to the main array also.

This method allows you to define JSON objects within an array. Usage: array = [ {a:1},{b:2} ] Example: array = [ {a:1},{b:2} ] echo array[0].a echo array[1].b Result: - 1 - 2

Returns a select section of a string. options are required in the substr brackets "substr(options)" Usage: string.substr() In the Example below the options are "0, 4" this will start the new string at char "0" of the existing string, and end it 4 chars after. Example: theString = "NEAT Bot" echo theString.substr(0, 4) Result: NEAT CategoryFunctions
