Code splitting

Code splitting is the practice of splitting the code a web application depends on — including its own code and any third-party dependencies — into separate bundles that can be loaded independently of each other. This allows an application to load only the code it actually needs at a given point in time, and load other bundles on demand. This approach is used to improve application performance, especially on initial load. Code splitting is a feature supported by bundlers like webpack and Browserify which can create multiple bundles that can be dynamically loaded at runtime.
