10 Best Scala Tutorials for Beginners [2024 JUL]— Learn Scala Online

Learn Scala programming to build imperative, logical, functional, and OOP skills with the best Scala tutorials for beginners in 2024.

Apache Spark gives us unlimited ability to build cutting-edge applications. It is also one of the most compelling technologies of the last decade in terms of its disruption to the big data world.

Apache Scala Spark provides in-memory cluster computing which greatly boosts the speed of iterative algorithms and interactive data mining tasks.

Apache Spark is the next-generation processing engine for big data.

Tons of companies are adapting Apache Spark to extract meaning from massive data sets, today you have access to that same big data technology right on your desktop.

Apache Spark is becoming a must tool for big data engineers and data scientists.

1. Learn By Example: Scala

• Scala is cool because its all the rage for big data applications, and because it manages to be more sophisticated and elegant than Java.
• That said, Java is a steady, reliable friend — a language you can depend upon, and in which you can express yourself.
• These 65 examples will help you trust Scala the way you trust Java. Each is self-contained, has its source code attached, and gets across a specific Scala use-case. Each example is simple, but not simplistic.

2. Functional Programming Principles in Scala

Functional programming is becoming increasingly widespread in industry. This trend is driven by the adoption of Scala as the main programming language for many applications.

In this course, you will learn how to:

• discover the elements of the functional programming style.
• apply the elements usefully in your daily programming tasks.
• develop a solid foundation for reasoning about functional programs, by touching upon proofs of invariants and the tracing of execution symbolically.

You will learn the difference between functional imperative programming. You will step through the basics of Scala; covering expressions, evaluation, conditionals, functions, and recursion.

You will learn about functions as first-class values, and higher order functions. You will also learn about Scala’s syntax and how it’s formally defined.

You will learn about methods, classes, and data abstraction through the design of a data structure for rational numbers.

You will cover traits, and learn how to organize classes into hierarchies. You will cover the hierarchy of standard Scala types, and see how to organize classes and traits into packages.

You will touch upon the different sorts of polymorphism in Scala. You will learn about the relationship between functions and objects in Scala; functions are objects!

You will zoom in on Scala’s type system, covering subtyping and generics, and moving on to more advanced aspects of Scala’s type system like variance.

Finally, you will cover Scala’s most widely used data structure, Lists, and one of Scala’s most powerful tools, pattern matching.

Get your data to fly using Spark and Scala for analytics, machine learning and data science

Let’s parse that.

What’s Spark? If you are an analyst or a data scientist, you’re used to having multiple systems for working with data. SQL, Python, R, Java, etc. With Spark, you have a single engine where you can explore and play with large amounts of data, run machine learning algorithms and then use the same system to productionize your code.

Scala: Scala is a general purpose programming language — like Java or C++. It’s functional programming nature and the availability of a REPL environment make it particularly suited for a distributed computing framework like Spark.

Analytics: Using Spark and Scala you can analyze and explore your data in an interactive environment with fast feedback. The course will show how to leverage the power of RDDs and Dataframes to manipulate data with ease.

Machine Learning and Data Science : Spark’s core functionality and built-in libraries make it easy to implement complex algorithms like Recommendations with very few lines of code. We’ll cover a variety of datasets and algorithms including PageRank, MapReduce and Graph datasets.

What’s Covered:

Scala Programming Constructs: Classes, Traits, First Class Functions, Closures, Currying, Case Classes

Lot’s of cool stuff ..

• Music Recommendations using Alternating Least Squares and the Audioscrobbler dataset
• Dataframes and Spark SQL to work with Twitter data
• Using the PageRank algorithm with Google web graph dataset
