Course description

Introduction to TypeScript | TypeScript Quick Start

Introduction to TypeScript is a hands-on course geared for web developers who need to learn basic TypeScript to use with today's systems and architectures to build sophisticated web interfaces.  The training will guide students through a balanced mixture of theory and practical labs to gain core development skills and have them explore its related technologies through to the use of tools and libraries to ease the development of advanced web applications.  Course attendees will be able to hit the ground running right after class, applying essential TypeScript to projects at both an architectural as well as a line by line coding level.  

Throughout the course, students will explore the practical use of the umbrella of technologies that work in conjunction with TypeScript as well as some of the tools, toolkits, and frameworks that can be used in conjunction with web development and deployment. The course begins with an initial look at TypeScript and how it is used within the context of web applications, walking students through the different technologies that are used with TypeScript, and exploring core aspects of TypeScript in terms of web applications, security, tools, and frameworks.  

Learning Objectives

This skills-focused course is approximately 50% hands-on lab to lecture ratio. Our instructors are highly experienced practitioners who bring years of current "on-the-job" experienceinto every classroom. Working within in a hands-on learning environment guided by our expert team, attendees will learn to:

  • Understand what JavaScript is and how it is used within the context of web applications
  • Work with the different technologies that are the foundation for web applications.
  • Understand and work with the fundamental aspects of JavaScript in terms of web applications, security, tools, and frameworks
  • Learn to how to effectively work with the newest advances in JavaScript such as ES6 and TypeScript
  • Develop code using conventions and optimal constructs for performance
