Functions

Function	Type	Description
push	array	Adds one or more elements to the end of an array and returns the new length of the array.
pop	array	Removes the last element from an array and returns the value of that element.
unshift	array	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	array	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.

push

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:

a,b,c,d
a,b,c,d,e
5

pop

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:

a,b,c,d
a,b,c
d

unshift

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

shift

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:

a,b,c,d
b,c,d
a

concat

Usage: array123 = array1.concat(array2,array3)

used to join two or more arrays together.

Example:

boy = ["Luke", "Bob","Jason"]

girl = ["Emma", "Katie", "Chiara"]

uni = ["Jordan","alex","Jessie"]

names = uni.concat(girl,boy)

echo names

Result:

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

-These should be written in the following formats: 
 .''variable.function(arguments)'', example - ''myVar.subStr(3,2)'' if your variable name was "myVar" and you wanted to use subStr() to find the 2 characters that begin 3 from the left.

 .''object.function(arguments)'', example - ''city.coords.split(",")'' if you wanted to split the coordinates of your city into an array to determine the seperate x and y values using the split() function.
