    Study Notes

    Overview of Programming Languages

    • Formal languages used to instruct computers.
    • Enable creation of software, scripts, and executable instructions.

    Categories of Programming Languages

    • High-Level Languages

      • Abstract from machine code, enhancing human readability.
      • Examples include Python, Java, C#, and Ruby.

    • Low-Level Languages

      • Closer to machine code, offering greater hardware control.
      • Examples include assembly language and machine code.

    • Mid-Level Languages

      • Merge features of high-level and low-level languages.
      • C is a primary example.

    Types of Programming Languages

    • Procedural Languages

      • Emphasize a sequence of instructions.
      • Notable examples: C, Fortran, Pascal.

    • Object-Oriented Languages

      • Organize code into objects and classes, promoting reuse.
      • Examples include Java, C++, and Python.

    • Functional Languages

      • View computation as mathematical function evaluations.
      • Examples: Haskell, Lisp, Scala.

    • Scripting Languages

      • Usually interpreted and designed for task automation.
      • Common examples are JavaScript, Perl, and Bash.

    • Emergence of New Languages

      • New languages like Rust and Go focus on performance and concurrency.

    • Multi-Paradigm Languages

      • Many modern languages can support various paradigms, such as Python which includes procedural, object-oriented, and functional styles.

    • Domain-Specific Languages (DSLs)

      • Tailored for specific domains; for instance, SQL for database queries and HTML for web markup.

    Considerations for Choosing a Programming Language

    • Project Requirements

      • Assess performance, scalability, and maintainability needs.

    • Ecosystem and Libraries

      • Availability of libraries and frameworks to support development.

    • Community Support

      • Strong community backing and quality documentation enhance usability.

    • Learning Curve

      • The language's complexity and the familiarity of the team must be considered.

    Key Concepts

    • Syntax and Semantics

      • Syntax pertains to the structural rules of code; semantics relates to the meaning behind code.

    • Compilers vs. Interpreters

      • Compilers convert high-level code into machine code before execution; interpreters execute code line-by-line at runtime.

    • Typology

      • Strong vs. Weak Typing: Strong typing enforces strict data usage rules; weak typing is more lax.
      • Static vs. Dynamic Typing: Static typing checks types at compile-time; dynamic typing checks at runtime.

    • Python

      • General-purpose, high-level, prevalent in web development, data science, and automation.

    • Java

      • Object-oriented, platform-independent due to Java Virtual Machine (JVM), frequently utilized in enterprise applications.
