  1. Arrays allow us to store multiple values of the same type in a single variable, in a sequential order.

  2. Arrays are indexed starting from 0, and the [ ] are used to specify the index into the array. Therefore to access the first element of an array us [0], e.g. myArray[0]

  1. An array is in Javascript an object which you can understand as a list of values (could be numbers or strings). It is used if you want to store a lot of values from the same type (strings, values).

  2. When the variables name of the array is example, then you have access to the first element when you write example[0]

Questions
  1. A data type specifically for storing sequences of values.
  2. The first index of an array is zero, not one. Zero-based counting has a long tradition in technology and in certain ways makes a lot of sense, but it takes some getting used to.Think of the index as the amount of items to skip, counting from the start of the array.

  1. They allow to store multiple values of the same type within a single variable.
  2. The index to be used in that case is 0, similarly to the case in which one has to select the first letter of a string.

Arrays allow us to store multiple amount of values of the same type in a single variable.

The first element of an array is 0. We use the name of the array and hard brackets with the number of the element we want to return.

var fruits = new Array("apples", "bananas", "kiwis");
      console.log(fruits[0]);
      console.log(fruits[1]);
      console.log(fruits[2]);
      //--> apples
      //--> bananas
      //--> kiwis

  1. What do arrays allow us to do?
    Arrays allows us to store the same type of data for future use.
  2. What index should you use in order to access the first element in an array?
    Arrays start at 0, using myArray[0] would work to access the first element of the array.

1, allow us to hold more than one value in a variable.

2, you use an ordinal index to access the elements in an array. the first element will be 0, the second 1, the third 2, etc.

  1. using Array you can assign multiple values of the same type (integer, strings) to a variable, thus creating a list of objects inside of the variable.

  2. The fist element inside an array will have the index 0, as the last index of a list is the total number of elements inside the list - 1.

  2. The first index is [0] if you want to access the first array item you have to type for example:
