What are JavaScript Libraries for Bitcoin?

JavaScript libraries are collections of pre-written JavaScript code that developers can use to simplify and accelerate web development tasks. They provide ready-made functions, utilities, and components for handling common challenges such as DOM manipulation, animations, event handling, data formatting, and AJAX requests. By using libraries, developers reduce the amount of repetitive coding needed and ensure greater cross-browser compatibility. Many JavaScript libraries focus on specific areas, such as UI design, data visualization, or state management, making them versatile tools in both front-end and back-end development.
