Virtual Classes

About this event

React.js is one of the most popular front end frameworks. Companies like Facebook, Netflix, and Eventbrite are using it to power blazing-fast web apps that make interacting with users faster than ever before.

This is a three week, cohort-based class that will introduce you to the basic concepts you need to understand to work with React.js. This class offers 12 hours of instructional training and is limited in attendance to ensure for maximum instructor support. The class will meet six times on the following dates and times:


  • Monday, January 11th, 6::00pm-8:00pm PST
  • Wednesday, January 13th, 6:00pm - 8:00pm PST
  • Monday, January 18th, 6::00pm-8:00pm PST
  • Wednesday, January 20th, 6:00pm - 8:00pm PST
  • Monday, January 25th, 6::00pm-8:00pm PST
  • Wednesday, January 27th, 6:00pm - 8:00pm PST 


You'll learn why React is so powerful as a framework, work through exercises to learn the basics, and build an Instagram-like project from scratch. By the end, you will be comfortable with concepts such as React components, JSX, props, state, and basic React hooks, including the React Context API.


Basic familiarity with ES 6 - one of the more recent versions of Javascript. Specifically:

  • Variable declaration: const, let instead of var
  • String interpolation
  • Arrow functions
  • map() ...technically not ES6, but we’ll need it!
  • Destructuring objects and arrays
  • Imports/ Exports
  • Promises
  • Basic familiarity of HTML & CSS
  • Basic familiarity of Github (specifically, only need to know how to clone down a repository

All of the above ES 6 requirements will be covered in GDI's Intro to ES6 class, meant as a precursor to this React class.
