******************
Tokens:
These are the building blocks of the language, representing things like:
Identifiers: Names for variables, functions, etc. (e.g., x, myFunction). 
Keywords: Reserved words with specific meanings (e.g., if, while, for). 
Operators: Symbols that perform operations (e.g., +, -, *, =, /). 
Punctuation: Symbols like commas, semicolons, and parentheses. 
Literals: Constants, like numbers and strings (e.g., 123, "hello").
