It should be said that extjs is based on components with different granularities, while jquery mainly simplifies Dom operations.
If you look at the UI, you can use extjs. jquery can be used in any type of projects.
Let's take a look at the following:
Extjs saves you a lot of time on the interface, and almost no need to write it.Code, Using ext most of the time is learning how to use its API, even if you are not very skilled in JS, you can
It is used in the same way as Java. But if you want to modify the code or implementation of Ext, you basically have no way to start.ProgramThe JavaSource codeSame.
Jquery is not the same, it is very delicate, and the core + plug-in type development applications. you don't need to change the core. You can use plug-ins to complete the functions you need. If you don't have a ready-made plug-in, writing a plug-in by yourself is also very simple. at least, it is much simpler than Ext.

Different application scenarios. The latter is much more lightweight and has gained a lot of attention from Microsoft.
The former seems to be more powerful and beautiful for interface display.
Google's introduction gives you an overview of their respective purposes.
If you only want to understand and learn the scripting language, rather than go deep into front-end interface development, jquery is recommended.

Jquery
Both extjs and extjs have their own user groups. If they are applied to development of OA or web applications, extjs is advantageous because its UI is in the current
JS class libraries can be regarded as a leader, and the corresponding controls provided by him can basically meet the needs of most existing systems. For example, many systems in the telecom industry have adopted extjs. Of course
Jquery also has related UI plug-ins, but it is not comparable with extjs at present.
If you are developing Web websites, we recommend that you use jquery. jquery is relatively small, flexible, and easy to write, this depends on the implementation mechanism of the jquery framework.
Of course, from the perspective of simply learning JavaScript, you can learn extjs and jquery. But they all implement JavaScript frameworks at different levels.
