//How to print a specific element in javascript



/*====DESCRIPTION starts here=====
You can output a specific element or position of a list/array by 
using the output statement which is console.log(). Within it, type in the
name of the array in which you are dealing with, and specify with brackets
after the array name, enter the number of the 
position you want to output. Note though that as computers
count beginning from 0, you will have to subtract
1 from the original position we percieve. 
  ====DESRCIPTION ends here=======*/

//====EXAMPLE 1 STARTS HERE=========
//Using an integer to output a specific element/position of an array.
//array named "arr" which consists of 4 elements which are integers.
var arr = [3,4,5,2]
console.log(arr[2]) //Outputs "5" because 5 is the second (or third) element of the array.
//====EXAMPLE 1 ENDS HERE=========

//====EXAMPLE 2 STARTS==========
//Using a variable to output a specific element/position of an array.
//array named "arr" which consists of 4 elements which are integers.
var arr = [8,9,3,5]
//A variable named "i" which stores a value of an integer, 2.
	//Will be used to output the second element of the array.
var x = 0
console.log(arr[x]) //Outputs "8" since 8 is the 0 (or first) elemnt of the arary.
