jQuery
jQuery is the most widely-used JavaScript library, and is used in more than half of all major websites. It's motto is "write less, Do more...!"
jQuery makes web development easier to use by providing a number of 'helper' functions. These help developers to quickly write DOM (Document Object Model) interactions without needing to manually write as much JavaScript themselves.
jQuery adds a global variable with all of the libraries methods attached. The naming convention is to have this global variable as </code>. by typing in <code>.
