Thinking of building your own programming language? Start small. Focus on a niche use case—don’t aim to replace JavaScript on day one.
Understand the three parts: the lexer breaks code into tokens, the parser turns tokens into a syntax tree, and the interpreter or compiler executes it.
Choose a language like Python, C, or Rust to build yours in.
Use tools like ANTLR or Lex/Yacc to save time.
And most importantly — keep the syntax simple and consistent.
A great language doesn’t have to be complex, just clear and purposeful.
