Mobile javascript is banned

With the popularity of smart phones, the development of mobile Internet applications has led to the continuous updating and upgrading of mobile operating systems and development tools. Among them, Javascript, as an important client-side scripting language, is widely used in the development of various mobile applications, bringing users a convenient and efficient experience. But at the same time, some security risks have also emerged, so some people have proposed banning Javascript on mobile phones. Next let us discuss the rationality of this proposal.

1. Safety hazards of Javascript

In mobile applications, the main function of Javascript is to interact with the background server, dynamically render pages, and achieve various interactive effects. Among them, there may be some security risks in interacting with the backend server, such as cross-site scripting attacks (XSS attacks), cross-site request forgery (CSRF attacks), etc. These security risks can cause adverse consequences such as user information leakage, tampering or deletion of user data, and may even have a catastrophic impact on the entire system.

2. Advantages of banning Javascript

In order to avoid the security risks of Javascript, some people have proposed banning Javascript on mobile phones. This ban may have the following advantages:

(1) Improve the security of mobile applications. Disabling Javascript can avoid common security threats such as XSS attacks and CSRF attacks. It reduces the vulnerabilities of mobile applications and ensures the security of user information.

(2) Improve the efficiency of mobile applications. Disabling Javascript allows mobile applications to interact less with background servers, thereby improving access speed and response time.

(3) Improve the usability of the interface. Disabling Javascript can avoid excessive animations, scrolling, pop-up boxes and other effects, thereby reducing users' sense of confusion and fatigue when using mobile applications.

3. Disadvantages of banning Javascript

Banning Javascript can indeed improve the security, efficiency and ease of use of mobile applications, but it will also cause many problems and inconveniences.

(1) Functions are limited. Some functions based on Javascript cannot be used, such as calling location information, using cameras, creating maps, etc. This will cause many applications to not work properly and cause a lot of trouble to users.

(2) Development becomes more difficult. Banning Javascript will require rethinking the architecture and design of mobile applications, increasing developers' workload and development costs, and may reduce development efficiency.

(3) Incompatible with existing applications. Many existing mobile applications are built based on Javascript. If Javascript is disabled, these applications will not run, causing inconvenience to users.

4. How to reduce the security risks of Javascript

Currently, prohibiting Javascript may cause some unnecessary problems and inconveniences, so some methods to reduce the security risks of Javascript have been proposed. These methods include:

(1) Use safe coding standards. Coding standards can clearly stipulate the specifications and requirements of Javascript code, thereby reducing the possibility of security risks in the code.

(2) Use a secure web framework. Web frameworks can provide various security mechanisms and templates to reduce the probability of security risks.

(3) Use HTTPS protocol. User information can be encrypted and transmitted using the HTTPS protocol to prevent user information from being stolen by hackers.

(4) Call the client API interface. Many mobile terminals provide relevant API interfaces to avoid security risks caused by calling Javascript through the browser.

Generally speaking, banning Javascript can improve the security, efficiency and ease of use of mobile applications to a certain extent, but it will also cause many problems and inconveniences. Therefore, we should use other methods to reduce the security risks of Javascript and achieve more secure, efficient and convenient mobile Internet applications.
