Scala Designed by Martin Odersky in 2004, Scala is an open-source language facilitating a perfect blend of object-oriented and functional coding in a statically typed programming environment. Designed to address the cons of Java in terms of general-purpose, it can be an ideal Java alternative.
Market Popularity As per Google trends, there’s a surge in searches related to Kotlin as compared to Scala, giving a clear indication that Kotlin is more in trend. However, in terms of job posting, Kotlin is behind Scala by huge numbers.
Ease of Learning Scala is a powerful language with highly- advantages features and flexible syntax. So, it is quite difficult to learn this language. As for Kotlin, one can easily understand basic Kotlin syntax and start coding within 1-3 days.
Functional Programming Scala is more swayed by functional programming languages like Haskell than Kotlin. It encourages the use of functional coding along with some additional features like pattern matching and currying.
Pattern Matching Scala offers better opportunities for pattern matching than Kotlin. Its match statement enables developers to match any type of data, including its own. Also, it shows full support for higher-end and macros types.
App Performance Scala is a good option for employing highly scalableAndroid app development. Whereas, a Kotlin-based app will be easy to code and debug. Consequently, app performance will be higher in the case of Kotlin.
