Advantages and Disadvantages of JavaScript Language

JavaScript is the world's most popular programming language. According to Google, JavaScript language is the base for 95% of the websites on the internet.

Developers use JavaScript for frontend development and backend development. It is a great platform to make a potential website for your personal and organizational purposes. 

According to W. Clement Stone, “To every disadvantage, there is a corresponding advantage”

In this article, you will learn why JavaScript is so popular. I will also discuss the shortcomings of the JavaScript Language.

So, let’s get started!

Advantages of JavaScript Language

First, I will discuss some advantages of the JavaScript language. 

• Speed

The interpreted languages are much faster than the other languages. JavaScript is also an interpreted language. The compilation time of JavaScript code is way lesser than Java. JavaScript is a client-side scripting language, so it enhances the execution of code and saves time for the developers. JavaScript requires few minutes to connect to the server.

• Simplicity 

JavaScript is famous for its simple infrastructure. It is easy to understand and implement for both users and developers. You can perform dynamic functions on JavaScript and saves a lot of money. 

• Popularity

Since JavaScript can run on every browser, we have almost seen it on every website. Following are some websites that use JavaScript as a tool. 

• Google
• Amazon 
• PayPal
• Interoperability

Modern developers use JavaScript to develop different applications as it works perfectly with other programming languages. Developers use JavaScript code to add it to the other script. They also embed the JavaScript code in the other projects. 

• Rich Interface

As we know, the website design creates a first impression on the user. Developers use JavaScript language to make an attractive user interface. JavaScript also provides the facility to add sliders on the web page to make the web page catchier. You can also use JavaScript to add different UI elements to your website.

• Extended Functionality 

Modern developers use add-ons to make websites much faster. It saves their time and they make a lot of money. These add-ons comprise the pre-defined code. They just drag those codes and add them to the website script. The snippets and plugins are easier to use. By using them, developers make JavaScript applications faster than other programming languages.

• Versatile 

As I have mentioned above, JavaScript works as a frontend and backend development language. The best JavaScript framework for the frontend is REACT Native. While NodeJS is famous for backend development. You can build an entire website or application with JavaScript.

• Less Overhead

JavaScript enhances the functionality and performance of web applications by reducing the code. The developers use built-in functions for loops, DOM access. 

Disadvantages of JavaScript Language

Now, it's time to discuss some disadvantages of the JavaScript language.

• Client-side Security

Your website’s JavaScript code is visible to everyone. Anyone can pick a patch from your code and use it for malicious purposes. The viewers can also use your code for their own projects. It is not secure because anyone can change your website code without permission. Your website can face serious harm with these kinds of acts. 

• Browser Support

The browser interprets JavaScript code differently on various platforms. Some old versions of browsers don’t support some latest functions. If your client has an older version of browsers and you add the latest functions in the code, it will not run on the client-side. Developers must verify the code on different browsers to avoid complexities. 

• Lack of Debugging Facility 

Debugging is very important while developing a website. If you cannot find errors in the code, your application will fail after publication. Since some HTML editors provide the facility of debugging, they are not as efficient as other editors like C or C++. When the browser does not show any bug, it will be difficult to find the error for the developer.

• Does not Support Multiple Inheritance

JavaScript does not support multiple inheritances. There are some functions in Object-Oriented Programming (OOP) that require multiple inheritances. That’s why it is a flaw of the JavaScript Language. 

• Sluggish Bitwise Function

JavaScript stores the 64-bit floating-point numbers whereas it works on 32-bit numbers. At first, JavaScript converts the 64-bit number into 32-bit, operates on 32-bit, and then converts it to a 64-bit number. You can see so many conversions that taking place each time. It wastes a lot of time to convert numbers to integers. It increases the time to run a script on the browser and decreases the speed. 

Summary

After seeing the pros and cons of JavaScript Language, you can imagine the full picture of this field. JavaScript is a field that offers lucrative advantages whereas it has some drawbacks as well.

This blog tells you where to use JavaScript code to get maximum benefits. While using JavaScript, we may face potential problems with this language.

Using JavaScript language is very common nowadays. There are many big enterprises that use this language to develop their projects--- web applications, mobile applications, desktop applications, web development, etc.

As I have mentioned above Google is also working because of this amazing language.

I hope you have understood all the benefits and drawbacks of the JavaScript language. If you have questions regarding this, you can contact different websites for further details.
