    Ever wondered how the code you write is actually processed, parsed, and executed by your computer? 'Create a NEW programming Language from scratch' by Harshit Srivastava is an introductory journey into the fascinating world of language design and compiler construction. Designed specifically for ambitious programmers, computer science students, and software engineers, this practical course demystifies the entire pipeline of compiler design. Over the course of 1.5 hours of focused instruction, you will learn how to design, define, and construct your very own functional programming language from the ground up. The curriculum covers foundational computer science concepts including lexical analysis (tokenization), abstract syntax trees (ASTs), parsing strategies, and semantic analysis. By building your own compiler step-by-step, you transition from a developer who simply consumes languages to a creator who understands their inner machinery. Whether you want to design a domain-specific language (DSL) for your company or simply want to deeply understand how tools like Python, JavaScript, or C++ translate instructions, this course provides the perfect launching pad. No advanced compiler theory or PhD-level mathematics are required—just your curiosity and basic programming skills.

    What You'll Learn

    • Master the key phases of compiler design, including lexical analysis, parsing, and execution.
    • Construct a custom lexical analyzer (lexer) to convert raw source code into structured tokens.
    • Build a syntax parser from scratch to analyze source tokens and build Abstract Syntax Trees (ASTs).
    • Design the grammar, syntax, and operator precedence rules for your unique programming language.
    • Implement basic error reporting and validation mechanisms within your custom language parser.
    • Gain practical, hands-on experience applying fundamental computer science and compiler design concepts.

    Best For

    • Software engineers curious about the inner workings of compilers and interpreters.
    • Computer science students looking for a practical, hands-on introduction to language design.
    • Developers interested in creating custom domain-specific languages (DSLs) for their professional projects.
    • Programmers wanting to demystify how high-level code is parsed and executed.

    Not For

    • Learners seeking an advanced, deep-dive into complex compiler optimization techniques or PhD-level theory.
    • Beginners who do not yet have a foundational grasp of basic programming logic and control flow.
    • Individuals looking for a lengthy, multi-week academic course on formal language theory.
    • Developers who are strictly interested in building production-ready, general-purpose compilers for industrial use.
