Negative Impact of JavaScript

JavaScript is a wonderful language. It is one of the most significant languages of the modern coding world. It is easy to learn and implement. JavaScript has undergone several considerable developments in recent times to meet with the changing tides of time.

Here are some of the notable disadvantages of JavaScript. However, these disadvantages can also be mitigated.

Lack of Security

Javascript has codes that are visible to all the users sharing the code or viewing it. There is a high probability that certain users may use it for the wrong purposes. Such practices include using the source code with any authentication.

Moreover, it is straightforward to implement new code into the script and affect the overall security of the coding structure. It is one of the primary ways of data breaching a specific website, and no one could figure it out.

How to Protect JavaScript from Client-Side Security issues?

Runtime applications can act as a security shield for JavaScript against attackers. Runtime application is a new self-protection security technology that can create an environment and control, detect, and execute the application.

Some of the applications are combination anti-debugging and anti-tampering technologies along with other self-defensive capabilities.


The different web browsers interpret the codes of the script differently. For example, the way Chrome interprets a script is different from how Bing or Yahoo does it.

How to Mitigate It? 

Coders and users can run JavaScript on various browsers and platforms to understand the fundamental changes taking place in each venue. It is essential to note the similar features among all the browsers. Therefore, the changes can be separately coded for making them compatible with the various browsers.

Chrome users can update or add Node.js to their window JavaScript. Node.js is a platform built on the existing JavaScript of Chrome. It enhances the fast building of the network application. It is lightweight and efficient.

Lack of Debugging Facility

HTML editors can easily debug JavaScript and support them. However, the C/C++ editors do not feel efficient enough to like the HTML editors. Moreover, the C/C++ does not highlight the errors, and so editors cannot detect the problems.

How to Mitigate It?

There are several debugging facilities available to debug the errors. Coders can use simple program codes to generate debugger codes that can help them detect the problems. Displaying a complex set of objects in the form of a table can be helpful to see. Using functions like console.log and then scrolling through the list helps to determine errors quickly.

Slow Bitwise Functions

If the JavaScript consists of 64-bit floating numbers and the operator or the coder uses 32-bit operands, then a discrepancy can occur. The software usually converts these numbers to an integer of 64-bit JavaScript numbers, but the conversion process takes a lot of time. Therefore, too much time is wasted in the continuous conversion process.

How to Mitigate It?

The standard solution is to either use both the JavaScript version and the coder’s operand in 32-bit or 64-bit. Moreover, following Gen processors can help in faster conversion in less time.

Final Thoughts

Though JavaScript has several disadvantages, the list of advantages is enormous. We hope this article has helped you understand the common weaknesses of the software and how to mitigate them. Will you still use it? Do share with us!
