Master the fundamentals of JavaScript code

JavaScript is an incredible multi-functional language, often used for web development. Any interaction that happens on web pages is JavaScript in action.

On this four-week course, you’ll learn everything you need to know to create JavaScript applications and use JavaScript on web pages.

You’ll start with the fundamentals of the JavaScript language, such as setting up your environment, adding JavaScript to a webpage, and writing JavaScript code before exploring more advanced topics.

Unpack JavaScript operators

To help you build a strong foundation of knowledge, you’ll delve into the essential building blocks of JavaScript: variables and operators.

You’ll explore different variable data types to understand how to store and work with variable values in your scripts to make them dynamic.

Next, you’ll develop your understanding of operators and how they are used to modify variables or to tell us something about the variables. You’ll explore arithmetic, assignment, conditional, and logical operators and learn how to do basic calculations based on factors such as user input.

Investigate JavaScript classes and functions

To take your coding skills to the next level, you’ll learn how to use functions to structure your code. You’ll also explore classes, which provide another useful building block to help you structure your application better.

Finally, you’ll cover the built-in JavaScript methods to help improve the effectiveness of your code whilst saving time and complying with best practices for developing solutions.

Now you are familiar with many of the core features of JavaScript, you could develop your skills further by taking the Intermediate and Advanced JavaScript course here.

Skip to 0 minutes and 2 seconds Have you always wanted to learn more about JavaScript? You’ll almost certainly have come into contact with this ubiquitous programming language. If you have used a browser such as Chrome, Firefox, Safari or Edge, then you definitely have. JavaScript is all over the web. If you enter a web page and it asks you to accept cookies and you click OK, the popup disappears. This is JavaScript in action. This course has been developed in partnership with PACKT, in order to produce a guide on creating with JavaScript, no matter your level of experience. Adapted from material provided by experienced web developers with a comprehensive understanding of JavaScript.

Skip to 0 minutes and 45 seconds By studying just a couple of hours a week, this course provides an opportunity to learn from experts in their field, developing a deep understanding of JavaScript and enabling you to create interactive web pages and dynamic applications. More specifically, by the end of this course, you’ll be able to develop fun, interactive and dynamic JavaScript web apps, games and pages. Apply invaluable built-in JavaScript methods. Identify the method required to produce a certain outcome or solve a problem using JavaScript. Explain what JavaScript is, how it works, and what it is used for. Pretty much any interaction we have with web pages is because of JavaScript; the buttons you are clicking, birthday cards you are creating, and calculations you are doing.

Skip to 1 minute and 39 seconds So this is an immensely useful skill to master, particularly if you are interested in website development and design. Anything that requires more than a static web page needs JavaScript. And Studying on FutureLearn gives you the freedom to learn wherever you are, whether you are at home, on your commute, or on your lunch break. You can log in on your phone, laptop or tablet and pick up where you left off. Study how and when you choose.
