PowerShell vs Scala: What are the differences?
Introduction
PowerShell and Scala are both programming languages that are widely used in the industry. While PowerShell is primarily used for task automation and configuration management in Windows environments, Scala is a general-purpose programming language that is often used for building scalable and high-performance applications. Despite having some similarities, there are several key differences between PowerShell and Scala.
Syntax: PowerShell is based on the .NET framework and follows a scripting language syntax, with a focus on ease of use and readability. On the other hand, Scala is based on the Java platform and follows a more traditional object-oriented programming syntax, with support for functional programming as well.
Type System: PowerShell has a dynamic type system, which means that variables do not have to be explicitly declared with a specific type. This allows for more flexible programming but can lead to potential runtime errors. Scala, on the other hand, has a static type system, which requires variables to be explicitly declared with their types. This provides more robust type checking and can help catch errors at compile-time.
Concurrency and Parallelism: PowerShell has limited support for concurrency and parallelism, with features such as runspaces and workflows. However, it is mainly designed for single-threaded execution. Scala, on the other hand, has built-in support for concurrency and parallelism through its actor model and the Akka library. Scala provides powerful tools for building concurrent and distributed applications.
Libraries and Ecosystem: PowerShell has a rich set of built-in Windows-specific cmdlets and modules that make it easy to interact with the operating system and automate tasks. It also has a growing community and an active repository of open-source modules. Scala, on the other hand, benefits from a wide range of libraries and frameworks that are part of the Java ecosystem. This makes it easier to leverage existing code and tools when building applications in Scala.
Functional Programming: PowerShell has limited support for functional programming paradigms, such as higher-order functions and immutable data structures. Scala, on the other hand, is a fully functional language that provides powerful functional programming features, such as pattern matching, immutability, and higher-order functions. This makes it easier to write concise and expressive code in Scala.
Scalability and Performance: PowerShell is optimized for automation and task scripting, and it performs well in small to medium-sized tasks. However, it may not be the best choice for building large-scale applications that require high performance and scalability. Scala, on the other hand, is known for its scalability and performance. It can handle large amounts of data and is designed to take advantage of multi-core processors.
In Summary, PowerShell and Scala differ in their syntax, type systems, concurrency support, libraries and ecosystems, functional programming capabilities, and scalability and performance characteristics. While PowerShell is ideal for Windows automation and configuration management, Scala is a versatile language that is well-suited for building robust and scalable applications.

performance and scalability get a prototype going fast by keeping codebase simple find hosting that is affordable and scales well (Java/Scala-based ones might not be affordable)
I've picked Node.js here but honestly it's a toss up between that and Go around this. It really depends on your background and skillset around "get something going fast" for one of these languages. Based on not knowing that I've suggested Node because it can be easier to prototype quickly and built right is performant enough. The scaffolding provided around Node.js services (Koa, Restify, NestJS) means you can get up and running pretty easily. It's important to note that the tooling surrounding this is good also, such as tracing, metrics et al (important when you're building production ready services).
You'll get more scalability and perf from go, but balancing them out I would say that you'll get pretty far with a well built Node.JS service (our entire site with over 1.5k requests/m scales easily and holds it's own with 4 pods in production.
Without knowing the scale you are building for and the systems you are using around it it's hard to say for certain this is the right route.
We needed to incorporate Big Data Framework for data stream analysis, specifically Apache Spark / Apache Storm. The three options of languages were most suitable for the job - Python, Java, Scala.
The winner was Python for the top of the class, high-performance data analysis libraries (NumPy, Pandas) written in C, quick learning curve, quick prototyping allowance, and a great connection with other future tools for machine learning as Tensorflow.
The whole code was shorter & more readable which made it easier to develop and maintain.
