JavaScript Exercises: Top 9 Places To Practice Online

You might have heard people describe JavaScript as the language of the web, and you might have therefore decided to start learning it with the hopes of becoming a web developer. The truth is that - yes, JavaScript is one of the languages of the internet. It is used to create interactive elements, turning boring web pages into dynamic, exciting pieces. However, it is also used for a wide range of other things, including back-end development and mobile app development. Once you've started learning, one of the best ways to practice and improve your code is through simple JavaScript exercises. But where can you find such exercises?

1. Via BitDegree Interactive Course

Depending on your skill level, a BitDegree interactive course could be the best way to practice JavaScript courses online. Interactive courses allow you to not only learn JavaScript online but also to practice your existing JavaScript skills. They have such benefits as:

  • Interactive courses allow you to write code directly in your browser, simplifying things while you're still a beginner.
  • When you're working through an interactive course you will get feedback on your code as you go. This is a great way to help improve your skills and to learn new things.
  • The basic JavaScript exercises in most interactive courses are fun and engaging. This will help both keep your motivation and enjoyment levels up while you're learning.

A good example for such interactive course is the BitDegree's Interactive JavaScript tutorial.

Working through this course will provide you with a wide range of exercises to help practice your JavaScript. You will be guided through exercises that touch on all sorts of basic JavaScript concepts, including simple syntax, functions, and web development related exercises. Although this course does offer great JavaScript practice for people who are just starting, if you've already got more than beginner level knowledge you should take a look at a bit more advanced course.

Note: Working through these beginner JavaScript exercises if you've got a sound knowledge of JavaScript already won't cause any problems, you simply might find them too easy and somewhat boring. 

2. By Working Through The BitDegree JavaScript Guide

The BitDegree text-based JavaScript guide is also a great place to practice JavaScript exercises. If you've got a limited budget and can't afford some of the more expensive learning resources that are out there, this guide also provides a great way to learn JavaScript for free. If you're new to learning JavaScript, I would recommend starting from the beginning and working through this reference guide in order.

However, this guide might be better suited to people who already have at least knowledge and who simply want to practice completing JavaScript exercises online. The way it is structured allows you to explore different concepts and ideas separately. The JavaScript practice exercises for each concept are located right there on the page with the rest of the information. When you're having trouble with a specific concept or piece of syntax, all you need to do is head to the relevant page and have a look around.

Also, BitDegree Learn has a code editor, which means that you can practice JavaScript without downloading any kind of IDE. You can either create your own examples, or just click the "Try it Live" button in the guides and tinker with the already present examples. This can help you not only see how different methods work in JavaScript, but also to remember them for later use.

3. With The JavaScript Exercises On Hacker Earth

The Hacker Earth website offers two different types of JavaScript practice which are suited to different people of different skill levels. They include:

Simple Coding Challenges

Hacker Earth has one of the largest coding challenge libraries that I've found. It contains a huge variety of different types of Javascript practice exercises that are designed to help you practice and build your coding knowledge. In most cases, you will be given an end goal that you need to reach, a starting point, and in some cases, a few tips to help you along the way. How you reach your end goal is up to you, and this is one of the features that make these exercises so good for practicing JavaScript.

4. By Working Through The BitDegree jQuery Guide

jQuery is one of the most popular JavaScript libraries in the world. It is designed to help people put together more code faster and more efficiently. Since it is based on JavaScript, a lot of people claim that learning jQuery is a great way to improve your knowledge.

While working through the BitDegree jQuery Tutorial isn't the same as completing JavaScript practice exercises in the traditional sense, it will still give you plenty of JavaScript practice. As you work through the tutorial you will come across various JavaScript exercises. As a bonus, you also get to practice your HTML and CSS skills when you're working with jQuery!

If you're a complete beginner, you should work through the Interactive JavaScript Tutorial first, and then having a look at the text-based jQuery Tutorial. The basics of JavaScript that you will learn and practice in the first course will give you enough knowledge to learn jQuery. Practicing using jQuery will, in turn, reinforce and help you build on your JavaScript.

Of course, if you don't want some more direction when learning jQuery, BitDegree also has an interactive jQuery tutorial where you can learn theory and practice at the same time.

5. With Paqmind Challenges

Paqmind offers a wide range of JavaScript exercises. Along with JavaScript practice exercises, Paqmind also provides full answers and explanations - something extremely useful for inexperienced learners.

The thing that stands out is the fact that these exercises are somewhat different from most of the ones you will come across when you're trying to practice JavaScript online. They feature:

  • No sandboxes. This means that all of the work is done in your code editor, on your computer. While this is more difficult than writing code directly in your browser, it will help you practice using your code editor.
  • Exercises created by experts. Unlike many JavaScript exercise websites, the challenges on Paqmind are created solely by experienced programmers. You can rest easy with the knowledge that they're going to be accurate and high-quality.
  • Different formats. These include standard 'problem solving' JavaScript exercises, along with quizzes and other tasks.

Although they don't have a huge number of them, make use of Paqmind's exercises and other resources to help build your JavaScript knowledge.

6. By Working Through Practice Projects

One of the best ways to practice JavaScript online is to work through a range of different practice projects. Once you've built a solid foundation of JavaScript basics, practicing writing your code is one of the best ways to master the programming language.

Although practice projects can be found all over the internet, you need to be careful to make sure that they are:

  • Easy enough for you to complete.
  • Going to teach you and reinforce your existing JavaScript skills.
  • Not going to teach you bad habits or incorrect knowledge.

Some of these projects - like 'build a clock' and 'create your own game' - are mirrored in almost every JavaScript practice website that you'll come across. However, there is a whole range of other projects here that look interesting, exciting, and perfect for practicing your JavaScript!

Remember, don't try and undertake projects that are too hard to start with. Learning JavaScript takes time, and rushing yourself will only lead to frustration and other problems. 

7. With CoderByte Challenges

Another great website for finding JavaScript exercises is CoderByte. CoderByte is one of the most popular coding challenge websites in the world. It contains a huge variety of different exercises, each of which is designed to test different concepts or coding syntax.

However, the thing that gets CoderByte a place on this list is the fact that the majority of their JavaScript programming exercises are unique. Although only the first 20 or so challenges are free, a premium membership will give you access to hundreds more, as well as to complete solutions. This membership comes in at $35 per month, so it isn't super cheap. However, it could be worth paying for a month or two of access if you want to practice your JavaScript.

8. On Reddit

Although it doesn't offer 'JavaScript exercises' as such, Reddit is a great place to find a wide range of problems to solve, projects to practice with, and other ways to reinforce your JavaScript knowledge. One of the best places to find useful JavaScript information is via the Learn JavaScript Subreddit. Here you will find a huge community of learners sharing their learning experiences, asking for help with their code, and sharing different challenges and exercises for you to practice with.

9. By Answering Questions In Forums

Although they aren't the same as traditionally structured JavaScript exercises, answering people's questions in forums to be a great way to practice writing code. Head over to your favorite JavaScript forum (one example could be Stack Overflow), and look for people asking interesting questions. Choose one, take their question, and make it your goal to find the answer. Sure, this might take a significant amount of time or research, but the result will be more knowledge for you and a clear, concise answer for the person asking the question - everyone wins!

Remember to make use of BitDegree's JavaScript reference guide when you're doing things like this. 

Some last tips

JavaScript is one of the most widespread programming languages in the world. Its use as one of the 'big three' front-end web development language makes it very popular among beginners. This, in turn, leads to a large number of people searching for the best way to practice JavaScript online.

The best way to practice is by completing some form of JavaScript exercises. The type of JavaScript practice exercises that you choose will depend on you and your learning style, but you can choose from the ones outlined above. Interactive courses are a great place to start, while traditional 'coding challenges' are also useful. Try and answer questions in forums, work through text-based references, or even compete in a live challenge if you feel up to it!

Remember, learning JavaScript isn't something that you can do overnight. It takes a lot of practice, time, and commitment. Take things slowly, make sure that you're learning all the major concepts, and don't skip over anything. Complete online courses and JavaScript practice exercises when you have a chance. Most importantly, have fun!

Practicing is very important when it comes to learning a programming language. You can practice by entering online courses that provide practical JavaScript exercises.

How can I practice JavaScript at home?

You can learn JavaScript from your home, by reading JavaScript tutorials and guides. Moreover, you can study and get certificates from online learning platforms, that provide courses where you can complete JavaScript exercises. Also, you can find other resources to learn JavaScript at home.

How do you choose which online course sites to review?

We pick online learning platforms according to their market size, popularity, and, most importantly, our users’ request or general interest to read genuine MOOC reviews about certain online learning platforms.

How much research do you do before writing your e-learning reviews?

Our dedicated MOOC experts carry out research for weeks – only then can they say their evaluations for different aspects are final and complete. Even though it takes a lot of time, this is the only way we can guarantee that all the essential features of online learning platforms are tried and tested, and the verdict is based on real data.

Which aspect is the most important when choosing the best online learning platforms?

It wouldn’t be right to pick just one aspect out of the selection: priorities depend on each individual person, their values, wishes, and goals. A feature that’s important to one person can be utterly irrelevant to the other. Anyhow, all users would agree that good quality of the learning material is a must for online learning platforms.

How is this e-learning review platform different from others?

Every MOOC-reviewing platform is unique and has its own goals and values. Our e-learning reviews are 100% genuine and written after performing a careful analysis. That is the goal that a lot of e-learning review sites lack, so we consider it to be our superpower!
