In the world of web development, JavaScript has become the go-to language for building interactive and dynamic applications. It can also be run in the backend, it can be used for desktop applications, mobile applications, multipurpose programming and even Machine learning. However, the trend of using JavaScript for everything might not always be the best approach.

The JavaScript Craze

JavaScript's versatility and browser compatibility have made it an indispensable tool for creating modern web applications. From front-end interactivity to server-side logic, JavaScript has expanded its reach. The thing I hate about JavaScript is that it is somehow being used for stuffs that we shouldn't using (like Machine learning with JavaScript?).

The Downsides

While JavaScript offers numerous advantages, relying on it exclusively can lead to certain downsides:

Performance Overhead

Using JavaScript for complex tasks can lead to performance bottlenecks, especially on resource-constrained devices and slower networks. JavaScript is an interpreted language, which means that the code is executed line by line at runtime. This can lead to slower execution compared to compiled languages, as each line of code needs to be interpreted before it is executed.

Maintenance Complexity

As projects grow, JavaScript codebases can become hard to maintain and debug, increasing development time and costs. Maintenance complexity in JavaScript refers to the challenges developers face when managing and updating code over time. Due to JavaScript's dynamic nature, lack of strict typing, varying browser environments, and its inconsistency, maintaining JavaScript code can become complex.

Memory inefficient

One of the major drawbacks of JavaScript is its memory inefficiency. JavaScript can be memory inefficient due to factors like memory leaks, unnecessary object retention, and improper handling of large data sets.

Conclusion

JavaScript remains a powerful tool, but it's essential to use it
judiciously. I love JavaScript but the enthusiasm to use it
everywhere is mindboggling. Other languages exists for a reason. You don't have to use JavaScript for everything. Most of the newcomers in tech end up only learning JavaScript.
