I am 22, and I <i>have</i> used jQuery. I loved jQuery, and it was a fascinating library that solved a lot of problems. It is still a great library, if one needs to support legacy browsers.I also think that jQuery influenced the DOM API to some extent; good things were adopted, bad ones were improved.<p>However today, I don&#x27;t think it&#x27;s as useful—I am not saying it <i>isn&#x27;t</i> useful—as it once was. The overhead to support multiple modern browsers is usually very low, and often it&#x27;s even none.<p>I also believe most of the problems people point about jQuery is that at some point a lot of confident, but bad developers, started using it and somehow jQurey unjustly gained that bad reputation.
