Simplifying JavaScript: Basic Concepts for Web Development
Introduction to JavaScript
JavaScript, often called JS, is a powerful language for making websites interactive. When mixed with HTML and CSS, it makes web pages come alive.
Understanding JavaScript Basics
JavaScript basics are like the rules of the game. They include stuff like variables, which store information, and functions, which are like pre-made actions.
Adding JavaScript to Websites
To use JavaScript on a website, we put our JavaScript code inside <script> tags. This lets us control what happens on the webpage, like changing text or making things move.
Important JavaScript Ideas
Before we start coding, let's know some big ideas in JavaScript:
1. Storing Information with Variables
Variables are like containers that hold different types of information, like numbers or words. They help us keep track of things while coding.
1. Storing Information with Variables
Variables are like containers that hold different types of information, like numbers or words. They help us keep track of things while coding.
2. Doing Actions with Functions
Functions are blocks of code that do specific tasks. They can take inputs and give outputs, like mini-programs inside our main program.
3. Making Decisions with Conditions
Conditions help our code make choices. We use them to say "if this happens, do that" or "if not, do something else."
4. Repeating Actions with Loops
Loops are like the repeat button in coding. They let us do the same thing over and over until we decide to stop.
Starting with JavaScript in HTML
Now, let's see how to put JavaScript into an HTML page:
1. Adding JavaScript Code
We can write JavaScript directly inside <script> tags in our HTML file. We can put these tags in the <head> or at the end of the <body>
2. Playing with Website Elements
JavaScript lets us change what's on the webpage in real-time. We can grab things like text or buttons and make them do different stuff, like changing color or size.
3. Responding to User Actions
We can make our website interactive by listening to what users do. JavaScript lets us react when they click, move their mouse, or type something.
