Scala in 100 Seconds

Scala is a language that combines object-oriented and functional programming paradigms, designed by Martin Odursky. It is known for its concise syntax and ability to interoperate with Java. Scala's features include type inference, immutability, and functional programming constructs like higher-order functions and monads. The language is used in large-scale applications like Apache Spark and LinkedIn. To start with Scala, one needs to install the JVM and Scala compiler, and use SBT for building projects. Scala's functional features help in writing concise and safe code, reducing common issues like null pointer exceptions.
