React is a JavaScript library for building web user interfaces. It is one of the most wanted and loved web frameworks today. React makes it painless to create interactive UIs on top of web standards. This Introduction to React using JavaScript/ECMAScript training course teaches developers the skills they need to immediately use React to build modern applications. Attendees gain hands-on experience with the latest version of React and the tools for developing React applications.

Skills Gained

All students will learn how to:

  • Use a JavaScript package manager (either npm or Yarn)
  • Quickly understand the new JavaScript language features, including classes, modules, and arrow functions
  • Articulate what React is and why it is useful
  • Explore the basic architecture of a React application
  • Gain a deep understanding of JSX and the Virtual DOM
  • Use React components to build interactive interfaces
  • Create and validate forms using controlled components
  • Make HTTP calls to read or change data
  • Configure simple and complex routing
  • Implement React best practices

Prerequisites

All attendees must be experienced JavaScript developers with a fairly advanced understanding of JavaScript, including prototypes and functions as first-class citizens. If your group doesn’t yet have this experience, we could readily add one or two days to the beginning of your course to appropriately prepare them.

Great instructor, clear and concise course. Labs were easy to follow and worked perfectly.

Labs and the study materials provided for Architecting on AWS course are very easy to understand and explains all the topics required to pass the Associate certification.

Concise and good to follow along. Although it is a lot to take in under a short period of time.

I thought the course was informative and the tools to go over the material were very nice.

The instructor really took his time and made sure I was able to understand the concepts.
