Browser sniffing is a kludge that should be avoided when possible. It's best to sniff for the capability you want to use. Say you want to execute an XPath expression using document.evaluate(), but you don't know whether it's supported. Instead of sniffing for supported browsers, do this:

if (document.evaluate) {
    // go ahead and use it
} else {
    // browser doesn't support it; do something else
}
