/*
Declaration of a variable in a computer programming language is a statement
used to specify the variable name and its data type.
Declaration tells the compiler about the existence of an entity in the
program and its location. When you declare a variable,
you should also initialize it.
i.e: let name: String = ; (as long as there is nothing after the equal sign (=)
the variable has been declared.
Initialization is the process of assigning a value to the Variable.
Every programming language has its own method of initializing the variable.
If the value is not assigned to the Variable,
then the process is only called a Declaration.
i.e let name: String = "Hatake Kakashi" (This means the variable name has been
initalized using Hatake Kakashi.
