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.
