Is this your first time on HN? People will complain about anything and everything. They'll incessantly dismiss anything that they think they could have done better in a weekend.
There's this whole FUD around Javascript in general. If you didn't know better, you'd think there were client-side tools in other ecosystems where you didn't have to learn or credentialize in anything to build a full-featured client.
I’m saying explicitly he or she is making up problems that don’t exist. My presumption is they never used webpack or tried for a second and gave up. My theory is this user likes to parrot things about the JS scene. Upgrading webpack involved changing some things from an array to a keyed object or something. It was nothing. I’m not particularly smart or JS savvy.
