A course to master ES6 with special emphasis on improving your coding skills and solving practical problems.

ES6 in Practice

ES2015   *   ES2016   *   ES2017   *   Lots of Exercises

ES6 is Everywhere

Including Job Interviews and Open Source Code

ES6 comes with a lot of new features, focusing on making JavaScript more usable. Popular frameworks already come with ES6 support. More importantly, ES6 makes JavaScript more popular, which means to you that there will be more JavaScript-centric frontend and full stack positions available to you.

Above all, ES6 is fun. Allow me to show you how easy it is to use ES6. Verify that the lessons stay with you with some fun exercises.

Most JavaScript tutorials teach you the fundamentals, and then they leave you in front of a blank screen. Practical ES6 develops your problem solving skills, so that you will be able to get started with coding.

What is worse than spending money on a spiced up version of the official documentation? Wasting your time to process it, just to find out that 80% of the content does not apply to you. ES6 in Practice gives you information on getting started with a topic, and you can immediately put it into practice using the Workbook.

Stop learning how to apply hacks with JavaScript. Focus on writing understandable and maintainable code instead.

Fix REAL-WORLD problems in JavaScript

Focus on UTILITY,

not edge cases

Write MAINTAINABLE code that will make you successful on the job

Tell me more about my LEARNING EXPERIENCE

The goal of this course is to strengthen your problem solving skills by using the new features of ES6. You will focus on the parts of JavaScript you are interested in the most. After understanding the fundamentals, you will get some exercises that let you put theory into practice. You will also have access to reference solutions that enrich your knowledge.

Most examples were inspired by web applications I had worked on personally. This means to you that you will see real stories, real objects, and real variable names, not just another meaningless foo variable.

Is this course for me?

If you are looking for a course that

  • helps you develop your JavaScript problem solving skills
  • helps you understand JavaScript more deeply than just scratching the surface
  • helps you get rid of Underscore/Lodash, jQuery
  • helps you prepare for the JavaScript job interview
  • takes you from knowing ES5 to ES6

If you don't have any programming experience, I discourage you from buying the course, as you will need minimal experience in JavaScript to benefit from it. You should know what variables are, what the basic types in JavaScript are, and how to write basic statements and loops.

Don't worry if you are a beginner. The first quarter of the course will give you some quick wins that you will be able to put into practice, regardless of your experience.
