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.
Trends in Programming Languages
-
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.
Popular Programming Languages
-
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.
