Effective Programming in Scala from Coursera

Scala is an expressive, versatile, and safe programming language.

In this course, you will learn how to get the most out of Scala to solve common programming tasks such as modeling business domains, breaking down complex problems into simpler problems, manipulating data, or running parallel tasks.

Along the journey, you will also learn the best practices for writing high-quality code that scales to large applications, how to handle errors, how to write tests, and how to leverage a productive development environment.

This comprehensive, hands-on, course aims at leveling up your programming skills by embracing both functional programming and object-oriented programming. You will become familiar with the standard library and the common patterns of code used in the real world.

Each week contains about 1h30 of video lectures. Each lecture is a ~10 min video focused on a specific skill or concept. We always start by looking at concrete problems, and then explain how language features or libraries make you more productive to solve these problems in general.

Lectures are generally followed by a quiz to assess your progress. At the end of each week, a graded assignment inspired by real-world applications will give you an opportunity to put things in practice.

The course covers Scala 3, and it mentions the differences with Scala 2.

Reviews summary

Effective scala for professional programmers

According to learners, Effective Programming in Scala is a highly valuable course for professional developers looking to master the language. Students consistently praise the instructor's clear explanations and the challenging, real-world inspired assignments that effectively solidify understanding. While the course provides a strong foundation in both functional and object-oriented programming, covering topics like error handling and concurrent programming, some find its pace quite fast. It is best suited for those with existing programming experience who aim to write high-quality, scalable Scala code.

Covers essential Scala topics for modern development.

"Overall, a very solid introduction to Scala 3. The lectures are well-structured and cover relevant topics."

"The topics covered are highly relevant for modern Scala development. I appreciated the distinction between Scala 2 and Scala 3 features."

"I now feel much more confident writing Scala code for production after completing this course."

"I learned so much about reasoning about code, testing techniques, and leveraging the standard library."

Complex Scala concepts are made clear by the expert instructor.

"The instructor, Martin Odersky, makes complex Scala concepts incredibly clear and easy to understand."

"The instructor's expertise shines through every lecture. The way complex topics are broken down into digestible ~10 min videos is brilliant."

"The explanations are always concise, which helps greatly."

Features challenging, real-world assignments that solidify learning.

"The hands-on assignments are challenging but very rewarding, truly solidifying the learned material."

"The graded assignments are excellent and really push you to apply what you've learned."

"As a professional developer, the real-world assignment examples are incredibly valuable."

Some quizzes felt basic; setup guidance could be better.

"My only minor gripe is that sometimes the quizzes felt a little too basic compared to the complexity of the assignments."

"I wish there was more guidance on setting up the development environment initially, as I ran into some issues."

Requires strong programming foundation; moves at a fast pace.

"If you're not already familiar with functional programming paradigms, you might struggle. It's definitely for experienced programmers, not total beginners."

"I came into this with some Java experience but found it extremely difficult to follow. The jumps between concepts felt too large..."

"The content itself is good, but I found the pace quite fast, especially in later weeks. It assumes a lot of prior knowledge."

"This course presumes a certain level of comfort with advanced programming concepts and functional thinking."
