Arrays | MDN

We can arrange items inside of an array.

Declare an array using -> var arrayname =[item, item, item];

Call an item -> arrayname[index] will return the item at location index.

Collection of related items stored in the same container. Unlike Java, JS arrays can consist of items with different datatypes.
0 Indexed. Arrays store item beginning at location 0.

Methods

arrayname.includes(item) -> can be used to find out if some item is inside of an array. Returns true or false.
arrayname.push(value) -> adds the value at the end of the array
arrayname.pop(item) -> removes the value at the end of the array

Fizz Buzz

Fizz Buzz is a program that starts counting from 1. For multiple of 3, fizz is said. For multiples of 5, buzz. If this number is a multiple of 3 and 5, fizzbuzz is said.

My logic below

Keep an index.

If number % 3 = 0, fizz. If number % 5 = 0 , buzz. If number %3 ==0 && number %5 ==0, fizz buzz. Index++
