JavaScript è un linguaggio di programmazione che consente la creazione di oggetti complessi in un web page — ogni volta che una web page fa molto di più che semplicemente visualizzare informazioni statiche — visualizzando contenuti aggiornati su base temporale, mappe interattive, o animazioni grafiche 2D/3D, o scrolling video jukeboxes, ecc... ecc... — si può presumere che JavaScript è coinvolto.

Percorso di apprendimento

JavaScript è sicuramente[ arguably] più difficile da imparare rispetto alle tecnologie ad esso correlate, come HTML and CSS. Before attempting to learn JavaScript, you are strongly advised to get familiar with at least these two technologies first, and perhaps others as well. Start by working through the following modules:

Una pregressa esperienza con altri linguaggi di programmazione può essere senz'altro utile.

After getting familiar with the basics of JavaScript, you should be in a position to learn about more advanced topics, for example:


This topic contains the following modules, in a suggested order for working through them.

JavaScript first steps
In our first JavaScript module, we first answer some fundamental questions such as "what is JavaScript?", "what does it look like?", and "what can it do?", before moving on to taking you through your first practical experience of writing JavaScript. After that, we discuss some key JavaScript features in detail, such as variables, strings, numbers and arrays.
JavaScript building blocks
In this module, we continue our coverage of all JavaScript's key fundamental features, turning our attention to commonly-encountered types of code block such as conditional statements, loops, functions, and events. You've seen this stuff already in the course, but only in passing — here we'll discuss it all explicitly.
Introducing JavaScript objects
In JavaScript, most things are objects, from core JavaScript features like strings and arrays to the browser APIs built on top of JavaScript. You can even create your own objects to encapsulate related functions and variables into efficient packages. The object-oriented nature of JavaScript is important to understand if you want to go further with your knowledge of the language and write more efficient code, therefore we've provided this module to help you. Here we teach object theory and syntax in detail, look at how to create your own objects, and explain what JSON data is and how to work with it.
Client-side web APIs
When writing client-side JavaScript for web sites or applications, you won't go very far before you start to use APIs — interfaces for manipulating different aspects of the browser and operating system the site is running on, or even data from other web sites or services. In this module we will explore what APIs are, and how to use some of the most common APIs you'll come across often in your development work.
