What is the main difference between webpack and other build tools like gulp or grunt?
Webpack is a module bundler, though it is quite often used instead of Gulp or Grunt task runners. This advanced tool provides developers with control of spliting the modules, allowing them to adjust builds to particular situations and workaround solutions that don’t function properly out of the box.
Talking about Webpack vs Gulp vs Grunt performance, the two latter look into a defined path for files that match your configuration, while the Webpack analyzes the whole project. It looks through all the dependencies, processes them with loaders and produces a bundled JS file.
