1.The Arrays allow to put one or more than one integer or script inside a variable EXP: var animal= new Array(“Mammoth”," Rhinoceros", “Parrot”);

  1. The first element of the array is always on the most left side of the arrays and the number attributed to it is 0 to have access just use the index number zero ,to use the index call the variable value and put the number between two parentheses EXP: animal[0];

  1. What do arrays allow us to do?
    Arrays let you store multiple values within a single variable.

  2. What index should you use in order to access the first element in an array?
    Let’s say you have var colors = [“blue”, “green”, “yellow”];
    To access the first element, which is blue, you use index 0, cause in programming, you always begin the count at 0.

  1. What do arrays allow us to do?
    The Array object lets you store multiple values in a single variable. It stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
  2. What index should you use in order to access the first element in an array?
    The first element in an array variable always start at 0. So 0= 1, 1=2, 2= 3, 3= 4 etc.

  1. It allows to store a number of values in just a single variable. You could also say that it is a collection of data that is stored. For example;

var vegetables = new array(“cucumber”, “cauliflower”, “spinach”);

  1. The array begins it counting from 0 and so the first value/element you would use is 0. This type of index that arrays use is called ‘ordinal numbers’. Here is an example;

vegetables[0] is the first element
vegetables[1] is the 2nd element
vegetables[2] is the 3rd element
and so on…

    Arrays allow us to store multiple values in a single variable by storing a fixed-size sequential collection of elements of the same type.

  2. What index should you use in order to access the first element in an array?
    Array index at Zero, so we should use 0 index to access the first element of an array
