What is Scala?
Scala is a programming language that mixes two styles of coding into one, so small programs stay short while big ones stay organized. Its name means scalable, like a toy set that works for a tiny house or a whole city.

What is Scala?
Scala (short for "Scalable Language") is a modern programming language created by Martin Odersky and first released in 2004, designed to run on the Java Virtual Machine while unifying object-oriented and functional programming in one language.
Scala powers large-scale, data-intensive systems at companies like Twitter, LinkedIn, and Netflix, and is the language behind Apache Spark, the industry-standard engine for big data processing. Because it runs on the JVM, Scala code interoperates directly with existing Java libraries.
Note:
Scala developers are among the highest-paid in the industry, largely because of Scala's central role in big data infrastructure like Apache Spark -- learning Scala is a strong path into data engineering.

Common Mistakes
- Thinking Scala is a scripting language only, when it is a compiled language that runs on the JVM.
- Assuming Scala cannot use Java code, when it can call Java libraries directly on the JVM.
- Expecting Scala code to look like Java line by line, and adding semicolons and
void, when Scala usesUnitand usually needs no semicolons.
