HTML (HyperText Markup Language) is the standard markup language used to create web pages. It provides the structure and content of websites by using a system of tags and elements that tell web browsers how to display text, images, links, and other media.
JavaScript is a programming language that enables interactive web pages. It can update content, control multimedia, animate images, and much more. JavaScript runs in the browser and can respond to user events like clicks, form submissions, and keyboard input.
It's commonly used for:
1. Keep It Simple: Write clean, readable code that's easy to maintain.
2. Test Regularly: Check your work across different browsers and devices.
3. Performance Matters: Optimize images and minimize CSS/JS files.
4. Accessibility: Ensure your site is usable by everyone, including people with disabilities.
