javascript - When are you supposed to use escape instead of encodeURI / encodeURIComponent?

When encoding a query string to be sent to a web server - when do you use escape() and when do you use encodeURI() or encodeURIComponent():
Use escape:
escape("% +&=");

OR
use encodeURI() / encodeURIComponent()
encodeURI("www.google.com/?var1=value1&var2=value2");

encodeURIComponent("var1=value1&var2=value2");
