JavaScript frameworks are like pre-built toolboxes for web developers. Instead of writing every single line of code from scratch, frameworks provide ready-made components and structures for common tasks like managing user interactions, updating the display, and handling data. Using frameworks can significantly speed up development time, improve code quality, and make web applications more maintainable. For high school web design students, learning the basics of a framework is a valuable skill that can open doors to creating more complex and interactive websites.
Frameworks offer structure. They help organize your code, making it easier to understand and modify later. Popular choices include React, Angular, and Vue.js, each with its own strengths and learning curve. This worksheet will help you understand the fundamental concepts!
