Scala is a nice language, if you’re interested then go ahead and learn it – no one reasonable should try to stop you.

Do you need Java to learn Scala?

No. Both languages run the JVM, the Java Virtual Machine, but you can learn Scala without first learning Java. Both languages take a different approach. Scala is a functional language and Java is a object-oriented language.

Can I use Scala instead of Java?

Programs written in Scala require less code than similar programs written in Java. It is both an object-oriented language and a functional language. This combination makes Scala the right choice for web development. You can use Scala to execute Java code.

Is Scala easy if you know Java?

The Java language and Scala both run on the same platform. AFAIK Scala can call down to Java code quite easily, so if there is any real interest in learning Java to understand/leverage Scala, then it is to understand how this works and how you can best use Java code from within a Scala app.

Why is Scala bad?

It combines poor-support for generic types with a very ambitious type system. It really is the worst of many worlds. To avoid going on too long, Scala is just a failed experiment with a long enough feature list to attract naive programmers and functional newbies.

Is Scala worth learning in 2021?

Scala is worth learning in 2021 due to the following reasons: Supports object-oriented programming and functional programming paradigms. … Interoperability with Java: Scala can run on Java Virtual Machine (JVM) and interoperates nicely with Java code.

Is Scala difficult to learn?

Scala has a steep learning curve, according to some software engineers. There are many ways to do something in Scala, and it’s a language that promotes expression and flexibility. This can be great if you’re an experienced programmer, and especially if you have some familiarity with Java.

Future represents a result of an asynchronous computation that may or may not be available yet. When we create a new Future, Scala spawns a new thread and executes its code. Once the execution is finished, the result of the computation (value or exception) will be assigned to the Future.
