Description

Introduction

Scala Application is a powerful, multi-paradigm programming language that combines functional and object-oriented programming. It is used to build scalable, high-performance applications in various domains, from data processing and backend development to distributed systems and microservices. This course, Hands-on Scala: Building Real-World Applications, is designed to give you practical experience in using Scala for real-world projects. You’ll learn how to design and implement robust applications, integrate with databases, work with web services, and deploy applications at scale. By the end of this course, you’ll be able to use Scala to develop high-quality, production-grade applications.

Prerequisites of Scala Application 

• Basic understanding of programming concepts.
• Familiarity with object-oriented programming and functional programming (optional but helpful).
• Experience with any programming language (especially Java or Python) will be advantageous but not mandatory.
• A development environment with Scala installed (IDE like IntelliJ IDEA recommended).
• Basic knowledge of databases, HTTP, and web services is helpful but not required.
