                Array: A special type of object that represents an ordered list of values.
                 For example:

                var colours = ["Red", "Green", "Blue"];
                Function: Functions in JavaScript are also objects and can be assigned to variables, passed as arguments,
                 and returned from other functions.
                 For example:

                function greetings() {
                return "Hello, friend!";
                 }

                Date: A date object represents a date and time.
                 For example:

                var todayDate= new Date();
                RegExp: A regular expression is a pattern for matching strings.
                 For example:

                var pattern = /hello/i;

                2.5 STATEMENTS IN JAVASCRIPT

              In JavaScript, statements are commands or instructions given to the interpreter to perform specific actions. A
              script or program is simply a collection of such statements. Most modern web browsers come with a built-in
              JavaScript interpreter to execute these commands.

              While semicolons (;) are typically used to end a statement, they can be omitted if each statement is written
              on a separate line.
              JavaScript statements are made up of variables, keywords, operators, expressions, and comments — let’s dive
              into each of these components in detail.

              Variables

              A variable is a named storage location that holds a value, which can be updated later. JavaScript is a loosely
              typed language, meaning you don’t need to specify a data type when declaring a variable. The identifier
              refers to the variable's name.
              The syntax for declaring a variable in JavaScript is:

                  var <variable name> = <value>;
              where var is a keyword, <variable name> is a valid name for the variable and <value> is the value that you
              want to assign the variable.
              For example:

                  var myAge = 31;
                  var name = "Aarav";
