JavaScript for React & GraphQL Developers Course

Course Summary

The JavaScript for React & GraphQL Developers training course teaches students about the modern JavaScript features needed to perform efficient and effective React Component development.

The course begins with an ECMAScript and JavaScript Introduction. The course then dives into functions, arrays, and objects as well as classes and prototype inheritance. The selected features are covered thoroughly and in-depth through live, compelling coding and lecture coupled with lab exercises on prototype inheritance, closures, and promises, etc., within a web environment. The course concludes with lessons on asynchronous programming and modules.

The focus of the class is to prepare students for the Introduction to React and Introduction to GraphQL courses. Previous programming experience is required and knowledge of web programming is a plus.
