The javascript abstraction library JQuery which we mentioned several months ago has now reached version 1.0. Javascript libraries have been gaining popularity with the emergence of “Web 2.0” and JQuery is another useful tool. This one tries to simplify the way javascript code is written, allowing for simpler coding.
Libraries like JQuery do help in rapid web development, though there are arguments against multi–layered abstractions since it teaches nothing new to the developers that use them. But certainly, they do have their uses in programming if used properly.
