Developers may select both jQuery and Ext JS for the same project because of their strengths. jQuery is popular for its ease in manipulating the DOM, event handling, and interaction with AJAX. It would be preferred for tasks requiring simple scripting. Ext JS provides a rich set of UI components and a robust application framework, which are very helpful in building complex, feature-rich web applications.
Through a combination of these tools, developers can leverage jQuery to develop rapid simpler functionality and DOM manipulation and the complex components and application structure of Ext JS. A hybrid approach makes developers able to be flexible and effective while developing an application.
However, it's important to note that integrating both libraries requires careful management to avoid potential conflicts, especially since both frameworks may use the $ namespace. To prevent such issues, developers can use jQuery's noConflict() method, which releases control of the $ identifier, allowing both libraries to coexist without interference.
Additionally, when using both frameworks, it's advisable to ensure that jQuery operates within its own namespace and does not interfere with Ext JS components. This can be achieved by encapsulating jQuery code within specific scopes and avoiding direct manipulation of Ext JS-managed DOM elements.
