&quot;Another example is the Fetch API&quot;... That API has very limited cross-browser support. One of the largest reasons web frameworks exist is to bridge the gaps between browser incompatibilities&#x2F;offering legacy support.<p>I don&#x27;t know if this person has even really scaled and deployed a web application that must work across several browsers - especially older browser versions. I always wonder that whenever I see people bashing frameworks. Like the author said, start with asking why the framework was created. Just make sure you come up with the right answer to that question next time.
