Course Description

Comprehensive Course Description:

It’s true that Scala is not among the most-loved coding languages. But don’t let this minor discomfort bother you. Scala is doubtless one of the most in-demand skills for data scientists and data engineers. And the reason for this is not far to seek: The supply of professionals with Scala skills is a long way from catching up with the demand. 

The course Scala from Beginner to Pro is refreshingly different. The well-thought-out quizzes and mini-projects that cover all the important aspects will make your Scala learning journey that much easier. This course includes an overview of Hadoop and Spark with a hands-on project with Scala Spark. Right through the course, every theoretical explanation is followed by practical implementation.

This course is designed to reflect the most in-demand Scala skills that you will start using right away at the workplace. The course is:

  •  Simple to follow and understand.
  •  Expressive.
  •  Exhaustive.
  •  Practical with live coding.
  •  Replete with quizzes.
  •  Rich with state-of-the-art and up-to-date knowledge of this field.

The 6 mini-projects and one Scala Spark project included in this course are vital components of this course. These projects present you with a hands-on opportunity to experiment for yourself with trial and error. You get a chance to learn from the mistakes you commit. Importantly, it’s easy to understand the potential gaps that might exist between theory and practice.

Why Should You Learn Scala?

In today’s fast-paced, data-centric marketplace, learning and developing a new skill is the way to go. In this context, Data Engineering with Scala skills aligns to perfection with employer demand. Your prospects of a rewarding career with a handsome salary package are given. And this course will give you a core understanding of Scala and Spark, presenting you with an opportunity that ensures emerging career growth.

Scala, a power-packed language, has the capability to leverage most of the functions in Python, such as designing machine learning models. You can use this high-level language for an assortment of applications, from web apps to machine learning.

This competitively-priced course will teach you the essential concepts and methodologies of Scala. You will also learn a lot of practical implementations in Scala and Spark. The HD video tutorials are divided into 140+ brief videos, and the total runtime of the videos is 13+ hours.

Sure, Scala is a language that has many complexities. But the challenging learning curve of Scala is well worth the investment. So, without any further delay, get started with this course, as Scala makes programming less wearisome and more enjoyable.
