Statistics say that Javascript, as a client-side programming language, is used by approximately 98.8% of all websites worldwide. The programming language is used for various purposes and helps you create groundbreaking software solutions. You may or may not know that the most prominent web apps, for instance, Facebook, Twitter, YouTube, and the like, have been built using JavaScript. This guide will navigate you through intensive know-how on JavaScript best practices and tools, enabling you to embrace the optimal potential of this groundbreaking technology.

Let’s get started!

What Is JavaScript?

JavaScript is a platform-agnostic, object-oriented programming language used to make interactive web pages and software solutions. It enables development teams to create dynamically updated content, make use of animations, clickable buttons, pop-up menus, control multimedia, and the like. You can use JavaScript programming language for both client-side and server-side.

Languages like CSS and HTML are used to give structure and style to web pages; JavaScript is utilized to add interactive elements that can engage users. Need more clear insight?

Why Is JavaScript So Popular?

Almost every computing device we use today has some contribution from JavaScript. These devices may be Android, iPhones, Windows, Linux, Mac OS, and the like. There are so many reasons why JavaScript is that popular; however, here are some of them, if we name a few!

In order to ensure your JavaScript Code is efficient, bug-free, and maintainable, you need to follow the right practices. Some of the JavaScript best practices examples are avoiding Shorthand, strict mode, and the like. Here are some of the best JavaScript practices for writing high-quality JavaScript code.

Select A JavaScript Coding Style Guide, And Follow It

It isn’t necessary; however, you can set up your coding standards to achieve your goals. You should remember that various industry-accepted, ready-to-use JavaScript coding style guides have undergone comprehensive testing. JavaScript Style Guide for AirBnB, Google, and Idiomatic JavaScript can be some of the examples for the same.

You may be wondering why you should create and follow a style guide. A style guide is needed when an entire team of developers works on a single project. This is because, irrespective of the count of people working on a project, every code in a codebase has to appear as if it were created by a single person and not by a group. No matter whether you create a style guide or use a third-party one, the consistent code will be convenient to write, understand, manage, and debug.

Give Descriptive Names To The Functions And Variables

Make sure your code is interactive enough to understand, and whoever interacts with your code understands the terms of your procedures, variables, and additional code structure. Don’t forget to keep the words neither too long nor too short to ensure they convey your intent conveniently.

Besides, bear in mind that JavaScript is case-sensitive. The well-known naming convention made use of in JavaScript programming is camel case capitalization. Consider using upper camelCase for interfaces & classes and lower camelCase for methods & variables so that the code is convenient to read and understand.

Avoid Using Shorthand

There are individuals unaware of the negative impacts of Shorthand as a practice. You might be wondering why it is so, mightn’t you? This is due to the complexity of the code, and it tends to take longer to carry out the same commands.

Make sure you always make use of lengthier variable names and avoid the short ones, keeping your code simple to understand. Remain certain about your actions, review documentation continuously, be on the lookout for pertinent JavaScript code samples, and test the outcomes.

Make Use of Strict Mode

Since JavaScript is a dynamic programming language, there’s always feasibility for a missing variable to be generated and utilized without any visible problem. Once done, these mistakes are recognized only when they are looked into but not during execution.

Considering the above-mentioned conditions, you should use strict mode when you work with JavaScript or any other programming language like Ruby, Python, or the like. With strict mode, you get additional error checking that you would otherwise avoid, resulting in making the code safe.

Consider Avoiding JavaScript for Styling

Consideration of separation of concerns (SoC) is one of the most significant JavaScript coding practices. JavaScript enables you to modify CSS code automatically while making use of the appropriate style. It’s recommended to circumvent it, keep the debugging procedure simple, and enhance code maintainability. Besides, you may consider adding and removing classes availing of the ClassList API as an alternative.

Leverage the Spread Operator

Leveraging the Spread Operator is one of the best JavaScript practices. Have you ever found yourself in a circumstance where you needed to provide an array’s whole contents as an individual element to another function or to put the whole content of one collection to another? That’s when using the spread operator comes in handy. It allows and supports the competencies to act similarly.

Comment Your Code, But Don’t Forget to Keep It Short

Commenting is a widespread issue in programming. People may think that it doesn’t matter, but the reality is without comment, a code is more likely to be difficult to read, specifically when working on a legacy project.

Furthermore, lengthy and wordy comments aren’t necessary– as reading and comprehending them tends to be more complex and time-consuming. As a common guideline, comment on everything on your code, specifically classes, functions, interfaces, and objects, but don’t forget to only provide essential details and keep them as short as possible.

Now that we’ve discussed the best JavaScript practices, we’re to move forward and explore some of the Javascript Development Tools. Being aware of mere practices may not be enough; hence, an overview of the tools used by mobile app development companies is essential. So, without further ado, let’s get started!

Final Thoughts:

That’s all there’s to it! In order to create software that meets your expectations, there’s a need to follow the time-tested practices. Apart from this, utilizing ideal tools is essential. Considering this fact, we’ve created this article consisting of JavaScript best practices and tools to assist you in being aware of what to do and creating an app that meets your needs.
