Why wouldn't you learn JavaScript?

There are close to 300 programming languages in the world, but JavaScript is almost essential education for any coding career. It is present everywhere -- from a humble PDF file to the internet of things. Everyone needs a bit of JavaScript and more so today as it has grown up from a simple client-side scripting language to a flexible programming language.

The internet wouldn't exist without JavaScript.

I could be wrong but I strongly feel that JavaScript has some of the best learning resources online. And you only need a notepad to begin your education!

Start and speed through the learning curve with these five popular courses from Udemy.

From now through 9/21 at 6:00am PST, you can get $15 off all courses with the code CHANGEUP15.

1 Hour JavaScript

Discover -- Why you should start learning JavaScript.

Skill Level -- Beginner.

You don't need anything expensive to learn one of the more in-demand coding skills today. Just the Chrome browser, a good internet connection, and a yen for web development. This is a course for complete beginners and is a good foundation to learn programming without the stress.

Cover 18 lectures in one-hour. The lectures won't overwhelm you so you can get a good handle on how JavaScript makes a static website functional. This is basically a crash-course with a few simple lines of code. Ideally, this course would have been free but then it takes effort to make them in the first place.

If you are hesitant about your commitment, take a look at the troika by including the 1 Hour HTML and the 1 Hour CSS courses too.

JavaScript for Beginners Learn by Doing Practical Exercises

Discover -- The preparatory steps before a more advanced course.

Skill Level -- Beginner.

There is only one way to learn coding. Apply what you learn and see it functions right before your eyes. Edwin Diaz is an experienced JavaScript instructor who takes you through the variables and loops with practice exercises. No, you won't become an expert after 3.5 hours but you will surely feel more confident about tackling the bigger challenges that lie ahead.

You will need a little knowledge of HTML before you start the lectures. Get introduced to variables, functions, arrays, loops, conditional logic, and math operations. Practice files, quizzes, and exercises should hold you in good stead.

JavaScript: Understanding the Weird Parts

Discover -- Advanced concepts such as closures, prototypal inheritance, IIFEs, and much more.

Skill Level -- Basic knowledge of JavaScript is required.

To imitate or understand. That is the perpetual quandary to learning new things. The former is a shortcut to knowledge while the latter gives you the master's grasp. This 12-hour course takes you under the hood so you get familiar with the more difficult concepts in the scripting language.

The provided "starter" code templates are a useful resource to practice with. Dive into advanced concepts as objects and object literals, function expressions, prototypical inheritance, functional programming, scope chains, function constructors, and new ES6 features.

For instance, this could be your first introduction to object-oriented programming. With the help of two sections, you will learn how easy it is to create and reuse code in your applications.

The aim of the lessons is to make you a better all-round developer who can also debug faulty programs with confidence. When you end up creating your own JavaScript framework then you are a good place in your journey. This course prepares you for other JavaScript based technologies like AngularJS, NodeJS, jQuery, React, Ember, and MongoDB.

Creating Responsive Web Design

Discover -- How to create websites that adjust on any screen size.

Skill Level -- Beginner.

Open a website on your tablet or just make your browser smaller. Did the webpage change dynamically to fit the new screen? This is responsive web design and it is pretty much a requirement for today's fragmented web. The person who hires you doesn't want to design multiple websites for different devices -- he wants you to design one website that fits any device.

You have to be part coder and part designer sometimes. Take this course and learn how to use HTML5, CSS3, and Media Queries to create designs that scale on any device. You will also learn how to make your site backwards compatible with old browsers. CSS, HTML, and Photoshop templates are provided in the lessons to help you practice the techniques.

The Complete Web Developer Course 2.0

Discover -- A lot more about web development and HTML based mobile app development.

Skill Level -- Beginner.

All your skills with HTML, CSS, and JavaScript will go into creating websites and HTML5 based mobile apps. This is a comprehensive course for beginners who want some umbrella cover with web development. How comprehensive? 289 video lectures spread over 31 hours.

Go hands-on by creating 25 responsive websites and real mobile apps. Start with basic websites built with HTML, JavaScript, and CSS. Then go forward with interactive websites made with jQuery, Bootstrap, and WordPress. Advanced lectures cover server-side coding using PHP7, Python, and MySQL.

The $200 entry fee might feel like a lot, but remember that this is a one-stop course that covers a huge chunk of web development. The lesson quality is top-notch and Rob Percival is a gifted teacher with an easy communication style. The course is extremely well-reviewed with over 66% of users giving it the highest possible rating.

Are You Interested in Learning JavaScript?

Make no mistake. JavaScript alone won't take you far in a programming career. A strong foundation with the likes of C, C++, Java, C#, Python, Ruby, PHP, and others is necessary. Also, learning different programming languages helps change the way you think about solutions.

Udemy is a good place to start because there are a large variety of courses. A course like ES6 JavaScript: The Complete Developer's Guide looks towards the future while free offerings like JavaScript Essentials could be the thing for hobbyist programmers who want to dip a toe into the water. Every paid course comes with:

• Lifetime access.
• 30-day money-back guarantee.
• Certificate of completion.
