When Will AngularJS surpass JQuery?

When DOM operations are secondary

JQuery focuses on DOM scanning and operations. A common example is to add and modify DOM elements through user operations. For example, add AJAX returned results to an existing DIV through pre-processed HTML. However, with AngularJS, the focus of development is data presentation. Through bidirectional data binding, data updates are automatically completed without the need to delete or recreate the DOM. Although DOM operations cannot be completely avoided, you only need to process less DOM operations when using AngularJS than jQuery.

When focusing on Efficiency

Although AngularJS is difficult to learn, it is highly efficient for developers. Many features of AngularJS focus on improving developers' output. For example, built-in extension support for unit testing is supported. Focusing on testing features by simplifying unit testing, developers can focus on producing more robust and reliable code. In addition, by decoupling DOM operations from program logic, developers can focus on "why" rather than "How to do ". This usually results in short, stable, and easy-to-Debug code.

When descriptive interfaces are used

A common problem with jQuery is that it uses imperative programming, which tells the computer how to achieve the goal, the result of such a process is what you want. However, descriptive programming, on the contrary, tells the computer the result you want and lets the computer determine how to implement it. In general, JavaScript is designed using imperative methods, while HTML-And AngularJS's instructions added to HTML-are designed specifically for descriptive programming. If you use AngularJS for programming, the descriptive programming that you finally adopt is more in line with the original HTML design intent-that is, to tell the computer what you want to display, the computer then processes the details. If this programming method is adopted, the number of lines of code required to complete a specific task will be greatly reduced. Such code is more readable and easier to maintain.

Conclusion

As mentioned above, AngularJS and jQuery are not comparable in many aspects. The two frameworks have different design objectives, so they have different solutions. Even so, the production capacity of some data display and maintenance applications developed by developers rather than data analysis applications has been greatly improved, and AngularJS is much better than jQuery in these fields. The final framework to choose is determined by the capabilities of your organization and many factors related to the core components of the tools used. However, AngularJS improves the productivity of Internet application developers in any case, the best choice for reducing maintenance costs.
