Part-5 | 01- Introduction to Javascript | Complete Course for Web Development |
JavaScript is a programming language that is primarily used to create interactive and dynamic web pages. It was first developed by Brendan Eich in 1995 and is now one of the most widely-used programming languages in the world.
JavaScript can be used to do a wide variety of things on a web page, such as:
Changing the content of a web page
Responding to user input
Validating form data
Creating interactive maps
Building browser-based games
And much more!
JavaScript code can be run directly in a web browser, or on the server-side using a JavaScript runtime like Node.js.
A simple example of JavaScript code is a script that changes the text of a web page when a button is clicked:
This script uses the document.getElementById method to access the button and text elements in the HTML, and then attaches an event listener to the button that listens for a "click" event. When the button is clicked, the event listener will run the function that changes the text of the web page.
JavaScript is often used in conjunction with other web technologies such as HTML and CSS. HTML provides the structure of a web page and the content, and CSS is used for styling and layout. JavaScript is used to add interactivity and dynamic behavior to the web page.
If you're interested in learning more about JavaScript, there are many resources available online, such as tutorials, documentation, and forums where you can ask questions and get help.
