# Compare Popular Imperative Programming Languages
Imperative programming, a paradigm that utilizes statements to alter a program's state, encompasses various popular languages.
This section categorizes popular[^popular1][^popular2][^popular3] imperative programming languages, comparing their robustness(bug preventation) and effectiveness(facilitating development).| Language | [Robustness][robustness] | [Effectiveness][effectiveness] |
| ------------------------ | ------------------------ | ------------------------------ |
| [JavaScript][javascript] | Moderate | High |
| [Python][python] | High | High |
| [TypeScript][typescript] | High | High |
| [Java][java] | High | Moderate |
| [C#][csharp] | High | High |
| [C++][cpp] | Moderate | Moderate |
| [PHP][php] | Moderate | Moderate |
| C | Low | Low |
| [Go][go] | High | High |In contrast, declarative programming, typified by languages like HTML, CSS, and SQL, follows a different paradigm that expresses computational logic without detailing control flow. However, this analysis will not cover declarative languages, as they are specialized and diverse in their objectives, with no two languages serving identical purposes.
## Robustness
The [robustness][^software_bug] of a programming language can be influenced by its approach to error prevention and handling.
### Bug Prevention
#### Typing System and Typographical Error Prevention
- ๐ **Static Typing** enforces type consistency at compile time. This system helps catch typographical errors early in the development cycle by ensuring that variables and functions adhere to declared types, leading to a more robust and error-resistant codebase. The compiler performs extensive checks for syntax, type correctness, and other potential issues, significantly reducing the risk of typographical errors causing runtime errors.
- ๐ **Dynamic Typing** determines types at runtime, which provides flexibility in coding but increases the risk of typographical errors. These languages rely on runtime checks, which means that errors, including those from typographical mistakes, are detected when the code is executed. This can lead to runtime exceptions if variable names or functions are incorrectly spelled.| Language | Typing System |
| ---------- | ------------- |
| JavaScript | Dynamic |
| Python | Dynamic |
| TypeScript | Static |
| Java | Static |
| C# | Static |
| C++ | Static |
| PHP | Dynamic |
| C | Static |
| Go | Static |#### Testing
Discusses approaches like unit testing and test-driven development (TDD).##### Unit testing
##### Test-driven development (TDD)
#### Programming language support
Presents a comparative overview of language features such as strong typing, memory safety, bounds checking, null safety, and concurrency primitives.
| Language | Strong Typing | Memory Safety | Bounds Checking | Null Safety | Concurrency Primitives |
| ---------- | ------------- | ------------- | ----------------------- | ----------- | ---------------------- |
| JavaScript | No | Yes | Runtime | No | Limited |
| Python | No | Yes | Runtime | No | Yes |
| TypeScript | Yes | Yes | Runtime | Yes** | Limited |
| Java | Yes | Yes | Runtime | Yes*** | Yes |
| C# | Yes | Yes | Runtime | Yes*** | Yes |
| C++ | Yes | No | Runtime | No | No |
| PHP | No | Yes | Runtime | No | Yes |
| C | Yes | No | Not standardly enforced | No | No |
| Go | Yes | Yes | Runtime | No | Yes |- **Strong Typing:**
- Prevents implicit conversions between incompatible types, reducing runtime errors due to unexpected type coercions.- **Memory Safety:**
- Languages with built-in automatic memory management like garbage collection, ownership or automatic reference counting (ARC)that helps prevent common memory safety issues. C++ and C do not have built-in automatic memory management, making them prone to memory safety issues without careful management(like using smart pointers).- **Bounds Checking:**
- Bounds checking is a crucial safety mechanism that prevents programs from accessing memory outside the allocated bounds of an array or similar data structures. This feature is essential for avoiding buffer overflows, a common source of security vulnerabilities and program crashes. Runtime checking will prevent buffer overflows but not automtically prevent crashes, this will work of the developer, or using language that have compile time checks like Rust. C does not provide built-in bounds checking, relying on manual checks by the developer or third-party tools for any form of bounds checking.
- **Null Safety:**
- TypeScript (Yes**): TypeScript incorporates null safety features like optional chaining (`?.`) and nullish coalescing (`??`), enhancing safety around `null` and `undefined`. However, these are compile-time checks.
- Java and C# (Yes***): Both languages have introduced features to address null safety, such as nullable reference types in C# 8.0 and Optional in Java, but require explicit adoption in code.
- **Concurrency Primitives:**
- "Limited" in JavaScript and TypeScript refers to the event loop model and async/await syntax, which are not traditional concurrency models but can handle asynchronous operations. Python, Java, C#, PHP, and Go offer more explicit concurrency support through various constructs like threads, async/await, goroutines, etc.### Bug Types
#### Resourcing
##### Uninitialized Variables
Presents how each language handles potential resource management issues.| Language | Uninitialized Variables |
| ---------- | ----------------------- |
| JavaScript | Forbidden |
| Python | Forbidden |
| TypeScript | Forbidden |
| Java | Forbidden |
| C# | Forbidden |
| C++ | Allowed |
| PHP | Forbidden |
| C | Allowed |
| Go | Forbidden |- **Languages Marked "Forbidden"**: For these languages, variables are either automatically initialized to a default value (e.g., `0` for integers, `false` for booleans, `null`/`nil` for object references) or the language requires explicit initialization at the point of declaration. This behavior prevents the use of uninitialized variables, thereby avoiding undefined behavior related to such use.
- **Languages Marked "Allowed" (C and C++)**: These languages allow variables, especially local variables within functions, to be declared without being initialized. Using these uninitialized variables can result in undefined behavior, as their initial values are indeterminate and can contain any bit pattern.##### Resource leaks
| Language | Resource Management Mechanism |
| ---------- | -------------------------------------------------------------------------------- |
| JavaScript | Manual management |
| Python | `with` statement for context management |
| TypeScript | Manual management |
| Java | `try-with-resources` for automatic resource management |
| C# | `IDisposable` interface with `using` statement for automatic resource management |
| C++ | RAII (Resource Acquisition Is Initialization) for automatic resource management |
| PHP | Manual management |
| C | Manual management |
| Go | `defer` statement for scheduling cleanup operations |[^software_bug]: https://en.wikipedia.org/wiki/Software_bug
## Effectiveness
Evaluates languages based on their versatility in various programming paradigms.
### Flexibility and Generality
The ability to use the language in a wide variety of programming paradigms and domains.
