Beginners Guide To 'Which programming language to...'

Ever wondered how to get into the programming world and which language to probably get acquainted with as per your area of specialization? What makes some languages suitable for complex tasks while others excel in simplicity?
By exploring various programming paradigms and compilation methods, this developer aimed to uncover the classifications that define our coding tools.

Basically, a few questions one may ask before settling include:

• ✨ What’s your main field/project? A versatile application or a specialized tool?✨
• 🔍 Which execution model do you find more suitable for your projects—compiled or interpreted?🔍
• 💬 Which programming paradigm do you prefer?💬
• 📊 What level of abstraction do you prefer working with? 📊

Let’s get into it.

1. Compilation Method: Execution Style

The method of execution impacts performance and flexibility:

Compiled Languages:
These languages are translated into machine code by a compiler before execution. This results in fast execution times.
Best For: Performance-critical applications, such as system software or games.
Examples:

• C++: Widely used in game development and performance-intensive applications, offering extensive libraries.
• Rust: Focuses on safety and concurrency while maintaining performance.

Interpreted Languages:
These languages are executed line by line by an interpreter at runtime, making them more flexible but typically slower than compiled languages.
Best For: Rapid development and scripting tasks where performance is less critical.
Examples:

• Python: Known for its simplicity and readability, widely used in web development and data analysis.
• JavaScript: Primarily used for client-side scripting in web applications, allowing for dynamic user interfaces.

Hybrid Languages:
Some languages use both compilation and interpretation to balance performance and flexibility.
Best For: Applications needing the speed of compiled languages and the flexibility of interpreted languages.
Examples:

• Java: Compiles to bytecode, which is then interpreted by the Java Virtual Machine (JVM).
• C#: Compiled to an intermediate language, running on the .NET framework.

2. Programming Paradigms: Different Approaches

Programming paradigms define the style and methodology of coding.

Imperative Languages:
Focus on giving the computer a sequence of tasks to perform. Code is written as a series of commands that change the program's state.
Best For: Tasks that require detailed control over the execution flow.
Examples:

• Java: Strongly typed and object-oriented, great for large systems.
• C: Offers low-level access to memory, ideal for systems programming.

Declarative/Domain Specific Languages:
Concentrate on what the program should accomplish rather than how to achieve it. The implementation details are abstracted away.
Best For: Situations where data retrieval or manipulation is the primary concern.
Examples:

• SQL: Used for querying databases, where the focus is on data rather than logic.
• HTML: A markup language that describes the structure of web pages.

Object-Oriented Languages:
Based on the concept of "objects," which can contain both data and methods. This encapsulation promotes organized and modular code.
Best For: Projects with complex data structures that benefit from inheritance and polymorphism.
Examples:

• C#: Known for its strong support for OOP and rich libraries, popular in enterprise applications.
• Ruby: Flexible and easy to read, used extensively in web development with Rails.

Functional Languages:
Emphasize the use of functions as the primary building blocks of code. They discourage side effects and mutable data.
Best For: Mathematical computations, concurrent programming, and situations where predictability is crucial.
Examples:

• Haskell: Purely functional, known for its strong type system and lazy evaluation.

3. Level of Abstraction: The Layers of Coding

Think of programming languages as layers of a cake:

Machine Language:
The base layer, made up of 0s and 1s. It’s what computers understand directly but can be tough for humans to read.

Low-Level Languages:
Closer to machine language, providing more control over hardware and memory management but requiring more complex coding.
Best For: System programming, embedded systems, and performance-critical applications.
Examples:

• C: Offers low-level memory access, commonly used in operating systems and embedded systems.

High-Level Languages:
Designed to be user-friendly, with syntax closer to natural language. They abstract away most hardware details.
Best For: General software development, rapid application development, and projects where development speed is crucial.
Examples:

• Python: Known for its straightforward syntax and vast ecosystem of libraries.
• Java: Provides a rich API and a robust framework for building applications.

Generally but not exhaustively, as seen programming languages can be categorized in various ways based on different criteria.
