An array is an ordered collection of elements of the same type, identified by a pair of square brackets [].
To use an array, you need to:
1. Declare the array with a name and a type. Use a plural name for array, e.g., marks, rows, numbers. All elements of the array belong to the same type.
2. Allocate the array using new operator, or through initialization, e.g.
int[] marks; // Declare an int array named marks
// marks contains a special value called null.
int marks[]; // Same as above, but the above syntax recommended
marks = new int[5]; // Allocate 5 elements via the "new" operator
// Declare and allocate a 20-element array in one statement via "new" operator
int[] factors = new int[20];
// Declare, allocate a 6-element array thru initialization
int[] numbers = {11, 22, 33, 44, 55, 66}; // size of array deduced from the number of itemshow to create an array in javascript

//Im using a let type variable for the example because it's what i reccomend
let exampleArray = ["Example", "Lorem Ispum Dolor", "I think you've got it"]
//Here's how you select a single object in the list
exampleArray[1]
/*In Javascript the arrays start counting at 0 which means i selected the 2nd
object in the list(Lorem Ispum Dolor) so if i wanna select the first array i
must type*/
exampleArray[0]
/*Now let's say you want to display it on the console, like let's say you are
coding in Node.js and you wanna see the value of the array.
P.S: In the example im gonna show all the values of the array.*/
