Webpack
Webpack is a module bundler. Webpack can take care of bundling alongside a separate task runner. However, the line between bundler and task runner has become blurred thanks to community-developed webpack plugins. Sometimes these plugins are used to perform tasks that are usually done outside of webpack, such as cleaning the build directory or deploying the build although you can defer these tasks outside of webpack.
React, and Hot Module Replacement (HMR) helped to popularize webpack and led to its usage in other environments, such as Ruby on Rails. Despite its name, webpack is not limited to the web alone. It can bundle with other targets as well, as discussed in the Build Targets chapter.
