. Discuss the advantages and disadvantages of using J Query in different project scales

Advantages

• The minimum amount of code to do the most things. It only takes few lines of code for developers to achieve amazing results. the developer need not check the client browser type without writing cyclic code, without writing animation function is complex, only through a line of code to achieve the effect can be.

• Performance. Although different version has many new features, the most streamlined version of the size of only 18KB. Each version of  J Query has a significant performance improvement.

• Plug-in Unit. Based on the development of J Query plug-ins currently has about thousands of. J Query is active and "rival" cooperation such as prototype. 

• Save the developer learning time. if we really want to learn J Query, developers still need to invest a little time. J Query does not require developers to put too much, can begin to develop rapidly, then gradually improve skills.

Disadvantages

• Bandwidth. It takes up a small amount of bandwith to download for the client/user of your website.

• Slow down. It also slows the operation of some takes-one can argue that some tasks are done fast in J Query compared to a naive plain JavaScript implementation.

• Better Alternatives. There are many other frameworks out there, that doesn't require J Query and if you're already using one of these, adding J Query might be an anti-pattern or just adding extra complexity that wasn't needed.
