JavaScript, dubbed as one of the most popular modern web technologies, paves the way for a more dynamic and interactive user experience on the web. We’re here to guide you through the basic concepts and exciting features of JavaScript and inject some life into your web pages!
1. What is JavaScript?
JavaScript is an incredibly adaptable and novice-friendly programming language. As you become more adept, you can venture into developing games, animated 2D and 3D graphics, comprehensive database-driven apps, and much more!
JavaScript is compact yet highly flexible. Developers have created a multitude of tools atop the core JavaScript language, unleashing an immense amount of functionality with minimal effort. These tools encompass APIs and third-party libraries which expedite the site building process.
2. JavaScript Basics
For a comprehensive understanding of the language, it’s essential to gain a grasp of the core JavaScript features that are standard in all programming languages. Getting comfortable with these concepts will give you a significant leapstart into other coding languages as well!
Variables
Variables are needed to produce anything of interest in programming. Values in JavaScript can range from Strings and Numbers, to more complex forms like Arrays and Objects.
let myVariable = 'Bob';
let myVariable = 10;
let myVariable = [1,'Bob','Steve',10];
let myVariable = document.querySelector('h1');
Operators
The working of JavaScript hinges on the understanding of its operators. These include Addition, Subtraction, Multiplication, Division, and other logical operators.
Conditionals
JavaScript conditionals add decision-making capabilities to the scripts. The simplest and most used form is If…Else.
let iceCream = "chocolate";
if (iceCream === "chocolate") {
alert("Yay, I love chocolate ice cream!");
}
else {
alert("Awwww, but chocolate is my favorite…");
}
Functions
Functions are blocks of code that are designed to perform a particular task. They are executed when invoked (called).
function multiply(num1, num2) {
let result = num1 * num2;
return result;
}
Events
JavaScript is tailored to react to events. A JavaScript can be executed when an event occurs, like a user clicking on an HTML element.
3. Enhancing Your Webpages
Learning the essentials paves the way to enhance your webpages. Add features like image changers or personalized welcome messages, utilize the Web Storage API to store data from the user, and incorporate DOM manipulations and events to raise the interactivity of your pages.
