You’re just out of loop. Webpack is the current big thing. It rose to prominence after grunt and gulp, which were both build automation tools. Webpack supplanted them by being a “one stop shop” for many of the things grunt and gulp were used for. However, as always happens, that convenience spiraled into increasing complexity as people wanted more and more out of their builds.
I would agree with this statement. You may not see Webpack directly because a lot of modern tooling/libraries/frameworks (whatever we're calling them now) have Webpack hidden away in their dependencies and the end consumer gets a hand full of useful cli commands that run magic.
