How do I compile and run a Scala code?

What can you do with Scala language?

What is Scala used for? A lot of things, ranging from machine learning to web apps. As a high-level general purpose language, Scala boasts an extensive range of possible applications. Scala allows developers to make good use of standard JVM features and Java libraries.


In what ways Scala is better than other programming language?

Advantages of Scala. The code is more concise, readable, and error-free. It is easy to write, compile, debug, and run the program in Scala, when compared to many other programming languages. Functional programming lets you approach the same problem in a different angle.


Is Scala programming hard to learn?

If you're interested in data science, and especially if you want to use tools like Apache Spark, learning Scala is highly recommended. Scala can be difficult to learn, especially without prior knowledge of Java or a similar language like C.


Which command is used to compile Scala programs?

How does Scala pass implicit value?

In simpler terms, if no value or parameter is passed to a method or function, then the compiler will look for implicit value and pass it further as the parameter. For example, changing an integer variable to a string variable can be done by a Scala compiler rather than calling it explicitly.Dec 7, 2021
