Tips and Tricks for JavaScript Developers

By Udit Agarwal


Maintaining the balance between code readability and optimization is essential. One must never make a compromise with the performance of an application. Creating a hurry in this process to market makes the situation get worsen. Performance is a critical factor in the success or failure of the web application. Frequent crashes and long waiting times can make customers annoyed.

We have mentioned some tips here to see dramatic improvements in the application’s performance.

Training Based on Long-Term Projects

Javascript development companies always fear to collide with their existing codebase. Maintaining a code in a project for several years can can facilitate more knowledge about software development. They can be sharp-firing but can be considered as quickly fading projects.

Decisions Affect the Entire System

Decisions of today can determine the long-term fate of the system. Now we generally ask ourselves, what changes can we make now? What needs to be improved? Sometimes, developers have the urge to start over from scratch. However, in most cases, it is challenging to identify issues with the current code. While the logic may be worth retaining, a different structure may be necessary.

Tips and Tricks for JavaScript Developers

Avoid Complex Structures

Big things are not inherently challenging. Every non-trivial project is a contamination of logic. In many cases, consideration and verification are must-have factors. There is an existence of lots of different data that needs to be processed. Difficulties arise from the intertwining of various issues. It is impractical to avoid all these factors altogether, but dissecting the problems into separate parts leads to a controlled combination. Let’s have a look at simple and complex data structures in JavaScript.


The most basic reusable piece of JavaScript code is termed a function. In particular, a pure function receives information and produces a return value. The function takes all the required data directly as parameters. The input data or data context does not modify. Such functions are easy to write, test, fix, and utilize.


The object is considered another complex structure. The most basic data structure maps strings to arbitrary values which do not include the logic. Functions become methods when attached to an object.

Objects in JavaScript are widespread and versatile. The data structure can be used as a parameter package with the involvement of multiple function handlers. For instance, you can put several similar functions on the same object and let them work with similar categories of data.


The most complex structure in JavaScript is named the class. The class helps establish the foundation for objects, and, at the same time, it also assists in enabling diverse entities. It is a mixture of prototype inheritance and object creation. Furthermore, it interweaves logic (functions) with data (instance properties). Sometimes a constructor function contains properties that are termed “static” properties. Templates such as “singleton” overload the class with even more logic.

Choice of Structures

Several recommendations from years of experience suggest using the most basic, flexible, and versatile structure: function. Using a pure procedure is best. One can avoid mixing data and logic in an object whenever possible. Also, one can ignore the use of classes. And they must perform one specific action whenever used.

Bottom Line

In conclusion, many tips and tricks can help JavaScript developers improve their coding skills and productivity. By following best practices and utilizing the tools and resources available, developers can write more efficient, maintainable, and scalable code.
