 // Why
 // - Variables are used to keep track of data that we want to use or change in our programs. They help us store values temporarily and reuse them later in our code.
 
-// Note
-// - To create variable you can use var, let and const keyword.
-// - `var` keyword has been deprecated so it's not recommended to use. Only use `let` and `const`.

 // - The fact that whenever we declare a variable and assign a value to it, it’s not the variable that holds the value but rather the variable just holds an address in the memory where the initialized value is stored. Further explaining, take for example:
 let age = 21;
 // - when we use age, it gets replaced with 21, but that does not mean that age contains 21, rather what it means is that the variable age contains the address of the memory location where 21 is stored.
