//* Values and Variable in JavaScript
//* ====================================

//* In JavaScript, values and variables are fundamental concepts that form the basis of programming.

//* Values:  A value is a piece of information that a program can work with. It can be a number, text, true/false, or more complex data. 
 
//* Variables: A variable is a container that holds a value. It has a name and can be used to store and manipulate data in a program.

// var myAge = 22;
// console.log(myAge);

//! Let's test
// var my_firstName = "John";
// console.log(my_firstName);

// var _myLastName$ = "Doe";
// console.log(_myLastName$);

// var 123myAge = 25;
// console.log(123myAge);

// var $cityName = "New York";
// console.log($cityName);

// var my@Email = "john@example.com";
// console.log(my@Email);
