<p> One thing the most visited <a href="/facts/Website/SAsjJnca">websites</a> have in common is that they are <a href="/facts/Website/SAsjJnca">dynamic websites</a>. Their <a href="/facts/Web_development/UW5ypSzj">development</a> typically involves <a href="/facts/Web_development/UW5ypSzj">server-side coding</a>, <a href="/facts/Web_development/UW5ypSzj">client-side coding</a> and <a href="/facts/Web_development/UW5ypSzj">database technology</a>. The <a href="/facts/Programming_language/cWTYbgWa">programming languages</a> applied to deliver such dynamic web content vary vastly between sites. </p> Programming languages used in most popular
