This is a good question. This really depends on the circumstances and what kind of things you are working on. I see that the web-based applications that assume heavy-traffic bandwidth will benefit from jQuery's size. All, or at least most developers will obviously benefit from jQuery's syntax, short learning curve, and the logical way in which jQuery works (it is possible to create multi-chained statements where each member function returns a jQuery object for the element you are working with, so that you can apply additional code to the elements that are returned).
سوال خوبیه . این خیلی بستگی به شرایط و نوع چیزی که دارید روی آن کار میکنید داره .
