  1. We use arrays to store a collection of data. An array (The array object) is a collection of variables of the same type. The parameter is a list of strings and integers. An array is created by assigning values.
  2. To access the first elelment in an array we should use 0, as arrays start counting at zero.

  1. Array are useful to create a set of different parameter of the same type, like the following:
    var array = [1,2,3,4];
    var array2 = [“apple”,“melon”,“banana”];
    to call one specific element of the array is needed to count correctly the element’s position,
    array2[2] is equal to “banana” because is the third element in the array.
  2. As explain above elements into the array are counted starting from “0”, thus to access the first element in an array one should use the number 0.

An array allows you to put multiple values in one variable
To call a specific value you need to use the var[0] for the first value in the variable and then go up from there based on location of variable in the string starting at position one(1) = [0] location.
