jQuery

jQuery

jQuery is a free, open source Javascript function library used to simplify HTML client-side scripting. Used in conjunction with Javascript, it can provide things like effects and animation with less effort.

jQuery has pros that include ease of use, quick to learn, large community of contributors, it easily traverses the DOM, and it simplifies the creation of effects. Cons of jQuery include: slowing down the client if excessively used, due to the handling of many functions, and the library does not include all functions.

Although jQuery is becoming obsolete, due to integrated frameworks in modern browsers that are able to accomplish the same tasks as jQuery, it still powers over 79% of the top 1 million websites in the world.
