scala VS Angular

Recently I had to revisit the "JVM languages universe" again. Yes, language(s), plural! Java isn't the only language that uses the JVM. I previously used Scala, which is a JVM language, to use Apache Spark for Data Engineering workloads, but this is for another post 😉.

Big Scala vibes here, see also [1].

Scala is the next-generation Java virtual machine (JVM) language that is rapidly gaining popularity as a modern alternative to Java.

Compiling Scala without a SAT solver is probably too difficult.

The CNF Converter is a gem.

In addition to Structured Query Language(SQL), we can also use a variety of different programming languages, such as Python, Java, JavaScript, R, Julia, Scala, or any other programming language as long as it supports a basic database connection and functions to perform all of those operations, to connect to databases and perform more advanced query operations on the data. This gives us greater flexibility and allows us to apply custom-created logic to the data.

Based on Lambda Calculus, developed by Alonzo Church in the 1930s, functional programming has been implemented in mainstream programming languages like JavaScript, Python and Java. Programming languages like Erlang, Haskell or Scala are better suited for functional programming as they are designed to be functional first.

Besides the dangers, mentioned by Angular docs (infinite loops, change detection errors), there is another thing, that might be quite nasty: effects are executed in a reactive context, and any code you call in effect, will be executed in a reactive context. If that code reads some signals, they will be added as dependencies to your effect. Here Alex Rickabaugh explains the details.

In June 2023, the Angular team raised a new RFC to implement control flow syntaxes within Angular. They gave the following rationale for introducing control flow syntax:

For scheduling, I use awesome code I found in the Angular source code.

Just to give you more context, I led the migration of several AngularJS applications to the newer Angular Framework. My client finally decided to make that move following the AngularJS deprecation announcement (stay up to date please 🙏)️.

Angular v17 was released some months ago with a ton of new features, a brand new logo and the new blog angular.dev.
