What is Code splitting?

Code splitting is a technique used in software development to divide an application's code into smaller, more manageable chunks or bundles. These bundles can then be loaded on demand or in parallel, rather than loading the entire application upfront. This can lead to improved initial load times, reduced resource consumption, and a better user experience, especially for large and complex applications. It's commonly used in web development with tools like Webpack, Parcel, and Rollup to optimize JavaScript applications.
