Tons. I've also used JavaScript to automate Adobe's products, extend Cheetah 3d, build web apps in node.js, and develop games in Unity 3d. JavaScript is far from perfect, but it's a nice language. Note that jQuery is great for fixing problems in the DOM APi, but it doesn't fix JavaScript (which has its own problems but no more than any other useful language). Much of jQuery is obsolete in modern browsers — events are handled fairly well in most browsers, and QuerySelectorAll replaces jQuery for most lookups. I don't like jQuery's iterators, but writing better ones is quite easy. PHP's problems are with its libraries (themselves far more horrible than the DOM API) and also the language itself. I do find PHP useful but its problems far outnumber JavaScript's.
