Install cs on Ubuntu 20.04/18.04 using the command: curl -fLo cs "$(uname | tr LD ld)" Manual installation of Scala 3 Option 1 – Install Scala 3 on Ubuntu 20.04/18.04 with CoursierĬoursier is a Scala installer tool whose main command is cs which ensures that JVM and standard Scala dependencies are installed and therefore becomes the simplest way to install Scala.In this guide, I will cover several methods to get Scala3 installed on your Ubuntu 20.04/18.04 system: Step 1- Install Scala 3 on Ubuntu 20.04/18.04 This guide demonstrates how to install Scala 3 on Ubuntu 20.04/18.04. ![]() For web development, Scala 3 has: Scalatra is a tiny, high-performance, async web framework, inspired by Sinatra, Lagom(a microservices framework), Scala.js(it provides a safer way to build robust front-end web applications), ScalaJs-React, Finatra e.t.c.It runs on the JVM (and in the browser).It has an expressive type system supporting Inferred types, Intersection types, Union types, Type lambdas, Open classes, Context bounds e.t.c.It has a dynamic feel but is a statically-typed language.It Java-compatible – interacts seamlessly with Java code.It’s a functional programming (FP) language.It has a concise,new and Shiny syntax – it has a readable syntax with new syntax foe control structures such as if, for, while e.t.c.Since Scala2 did not work so well for the community, Scala 3 has been created with many amazing features such as: Scala 3 incorporates the latest research and also the industry experience of Scala 2. It is a Java-compatible programming language such that the Scala and Java classes directly reference each other without any code needed.Īfter about 8 years of commitment and work scala 3 is finally out with more than 100 people contributing to this project. Scala is a high-level, object-oriented programming language with modern features such as closures, parametric types, virtual type members, and pattern-matching. ![]()
