Pros: huge community, tonnes of professional templates, themes and plugins (even free ones), relatively easy to use, consistent UI across browsers Cons: strongly tied to jQuery which is totally out of fashion, so much boilerplate it can become slow on larger website, not so easy to make non-trivial customizations to the style and behavior, oh, and did I mention jQuery? Would recommend mostly if you're looking for a quick solution to build a large website with minimal amount of coding
