This article mainly introduces "what are the powerful functions of Javascript". In daily operation, I believe many people have doubts about the powerful functions of Javascript. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "what are the powerful functions of Javascript?" Next, please follow the editor to study!

The powerful functions of Javascript are mainly reflected in the following seven aspects:

1. There is less interaction between the server: the user input can be verified before submitting the page to the server. This reduces the traffic of the server, which means saving money.

2. Give quick feedback to visitors: they don't have to wait for the page to reload to see if they forgot to type something.

3, automatically fix minor errors: for example, if you have a database system, the date format of the reservation is dd-mm-yyyy, and the format entered by the user is dd/mm/yyyy, an intelligent JavaScript script can correct this error before submitting the form.

4. Enhance ease of use by allowing visitors to change or interact with the user interface without reloading the page: for example, using JavaScript to shrink or expand a part of the page or to provide visitors with additional options.

5. Enhance interactivity: you can create interfaces that react when users mouse over or activate them using the keyboard. You can do this with CSS and HTML, but JavaScript gives you more support and a wider range of options.

6, the interface is richer: if users allow, you can use JavaScript to include some drag-and-drop modules and progress bars.

7. Make the environment lightweight: instead of downloading a large file like a Java applet or Flash movie, the script file is small and cached once loaded. JavaScript also uses browser controls rather than its own user interface to manipulate its functionality.

At this point, the study on "what are the powerful functions of Javascript" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
