There's no "running at..." distinction between the two. Both Java and JavaScript can run either on the server or on the client.
JavaScript is code in an HTML document(usually) that is not compiled.
Java, which is syntactically similar, is a strongly-typed OO language which is compiled and executes using the Java Virtual Machine (otherwise known as a runtime).
Java originated at Sun Microsystems. JavaScript originated as "LiveWire" at Netscape.
Learning either language certainly wouldn't *hurt*. ;-) The real learning curve in Java, though, is the API which isn't a factor in JavaScript.
