I trust you have learned JavaScript properly or you already know JavaScript enough to build a simple JavaScript-only web application. While the 16 concepts note below are neither complex nor difficult, you will understand them best if you already know at least some basic JavaScript.

  1. JavaScript Objects in Detail
  2. JavaScript Prototype in Plain, Detailed Language
  3. JavaScript Variable Scope and Hoisting Explained
  4. Understand JavaScript Closures With Ease
  5. Understand JavaScript Callback (Higher-Order) Functions
  6. Understand JavaScript’s “this” With Clarity, and Master It

Six Courses Coming Soon (Updated)

Don't learn JavaScript, Meteor, Node, Backbone, or any other web-dev technologies until you see our course offering or at least until you use our Modern Developer Technology Guide to determine which specific set of technologies you need to learn and use to accomplish your goals. Both are coming soon.

Each course is part of a Career Path, a complete web dev education. About 3 to 6 courses make up a Career Path. Note the following Career Paths you can choose from:

  • jQuery Developer/Designer, Junior Front-end Developer, Web Developer, or JavaScript Developer (2 courses)
  • The Modern Front-end Developer (3 courses)
  • Designer to Developer: Designer Building a Startup (3–4 courses)
  • The Front-end-Framework-Equipped Modern Front-end Developer (4 courses)
  • Full-stack Modern Developer (4–6 courses)
  • Startup-Bound Developer (Build complex database-driven startups like Facebook and Twitter) (4–6 courses)

First Ever JavaScriptIsSexy.com Courses

In a few weeks, look out for six comprehensive courses, unlike any you can find elsewhere online. Our Career Paths provide the best value—more comprehensive (we teach you everything), more relevant (latest and most apt technologies), and more affordable (~90% less than programming boot camps; ~99% less than college) than other similar courses, online or offline. You will learn more about modern web development (in 4–6 months) in our Career Paths than you would at any 4-year university.
  1. Course 1: Essential JavaScript and Modern Web Application Development

    You can't develop modern applications with just JavaScript.

    What You Will Learn
    In this course, you will learn beginning to intermediate JavaScript along with all the relevant and necessary technologies and tools to develop complete modern web applications on the front end. Note that JavaScript by itself is just about 35% of what you have to learn to develop modern web applications, even simple web applications.

    Who Is this Course For?
    — Anyone with at least some high school education
    — No programming experience necessary

    You will be able to develop complete moderately complex front-end web applications using JavaScript and other tools and technologies.

  2. Course 2: Mastering JavaScript and Modern Web Application Development

    Become a proficient modern JavaScript developer.

    What You Will Learn
    In this course, you will learn intermediate to advanced JavaScript along with all the relevant and necessary (intermediate to advanced) technologies and tools to develop complex modern web applications, though not database-driven apps.

    Who Is this Course For?
    — Completed at least the "essential" course

    What will graduating from this course allow you to do?
    Work as a jQuery Developer/Designer, Junior Front-end Developer, Web Developer, or JavaScript Developer. JavaScript and Web Developers with similar expertise can easily make $70,000 a year. (Salary varies by city and developer's expertise and experience.)

  3. Course 3: The Modern Front-end Developer

    Become a qualified Front-end Developer and make a huge salary or develop your own startup—if you take the "Skip-the-backend" course.

    What You Will Learn
    In this course, you will learn everything (except a specific front-end framework; see the next course) you need to learn to become a highly qualified Front-end Developer. You will learn not just JavaScript, but all the latest technologies and tools that modern front-end developers must know.

    Who is this course for?
    — Completed course 1
    — And graduated from course 2

    What Will Graduating from This Course Allow You to Do?
    Front-end developers are in high demand, perhaps more so than any other programmers, and they make more than $80,000 a year. (Salary varies by city and developer's expertise and experience.)

    We will prepare you for jobs and connect you with agencies and employers, when you graduate from the "Front-end Career Path."

    Of course you will be able to develop your own startup as well, if you take the "Skip the backend" course after this course.

  4. Course 5: Front-end-Framework-Equipped Modern Front-end Developer (Choose either React, Angular, Backbone, OR Ember)

    We will help you choose the best front-end framework for you. Don't waste time learning a front-end framework that's not for you.

    Advanced front-end developers with experience using at least one of the four noted front-end frameworks are undoubtedly the hottest (highly sought after) developers today. They make between $70K and $160K+. (Salary varies by city and developer's expertise and experience.)

  5. Course 6: The Modern Full-stack Developer

    Learn the technologies you need to know to become a qualified and successful full-stack JavaScript developer.

    What You Will Learn
    You will learn all the tools, skills, and technologies necessary to become a full-stack JavaScript developer.

    Who Is this Course For?
    — Completed the first three courses

    What Will Graduating from This Course Allow You to Do?
    You will be in high demand as a full-stack JavaScript developer, making between $70,000 and $160,000+ a year. You will be able to develop any kind of startup comfortably. (Salary varies by city and developer's expertise and experience.)

  6. Other courses are coming later, including a "Skip-the-Backend" course, courses on developing mobile apps for iOS and Android using JavaScript, and a course on developing iOS apps using Swift and other Apple technologies.

When Specifically Will the Courses Begin?

We will release the course web site, with more detailed information, in about 3–4 weeks (most likely in January). You can enroll in classes then.

The first set of courses may begin to roll out in February.

How Much Will Each Course Cost?

While we haven't finalized the cost for each course, I do know that we have different prices for the courses. For example, Course 1 will cost less than the Front-end course. Moreover, the cost per course will definitely be affordable to the working class. I will make certain the courses are affordable for most people. I will fight to keep Course 1 under $200, though I can't promise that I will win.

Get Ready! Between now and Christmas, enjoy the down time because, when our courses begin, they will kick your butt into web-dev shape. So get ready to work hard, build cool stuff, change the world (you will), and realize your dreams.
