Haskell vs PowerShell: What are the differences?

### Introduction
When comparing Haskell and PowerShell, there are key differences that distinguish these two programming languages. By understanding these differences, developers can make informed decisions on which language to use for their specific projects.

1. **Programming Paradigm**: Haskell is a purely functional programming language, which means its primary focus is on the evaluation of expressions rather than execution of commands. On the other hand, PowerShell is a scripting language that combines functional and imperative programming paradigms, allowing for both scripting and automation capabilities.
   
2. **Type System**: Haskell is statically typed, which means types are checked at compile time, ensuring better code reliability and preventing runtime errors related to data type mismatches. In contrast, PowerShell is dynamically typed, allowing for more flexibility but potentially leading to type-related errors at runtime.

3. **Syntax**: Haskell has a more mathematical and concise syntax, using indentation to denote code blocks and favoring immutability. In comparison, PowerShell has a more verbose syntax with a focus on simplicity and accessibility for system administrators and IT professionals.

4. **Ecosystem**: Haskell has a strong community and ecosystem focused on functional programming, with libraries and tools designed to support this paradigm. PowerShell, as a Microsoft-owned language, integrates seamlessly with Windows environments and has a rich set of built-in cmdlets and modules for system administration tasks.

5. **Performance**: Haskell is known for its high performance due to its immutable data structures and lazy evaluation strategy, making it efficient for certain types of applications such as mathematical algorithms. PowerShell, while versatile for administrative tasks, may not be as performant for computationally intensive tasks due to its scripting nature.

6. **Platform Compatibility**: Haskell is cross-platform and can be used on various operating systems, while PowerShell is primarily used on Windows but can also run on other platforms with certain limitations, affecting its portability across different systems.

### Summary
In summary, Haskell and PowerShell differ significantly in their programming paradigms, type systems, syntax, ecosystems, performance, and platform compatibility, making each language suitable for distinct use cases depending on the requirements of the project.
