JavaScript Best Practices — DOM Performance

Like any kind of apps, JavaScript apps also have to be written well.

Otherwise, we run into all kinds of issues later on.

In this article, we’ll look at some best practices we should follow when writing JavaScript code.

Too Many Interactions with the Host

We shouldn’t interact too much with any DOM objects.

They render slowly and we should reduce the number of interactions that are done.

Too Many Dependencies

If we have too many dependencies, then we should reduce them.

Over the years, many things are added to the JavaScript standard library.

So we don’t have to use 3rd party dependencies to do the same thing.

For instance, Lodash array methods can be replaced with built-in array methods.

3rd party HTTP clients can be replaced with the Fetch API.

Poor Event Handling

To improve performance of event handling, we should use them properly.

We should remove unnecessary loops and unbind unused event handlers with jQuery unbind or plain JavaScript’s removeEventListener to remove them.

Unorganized Code

To make our lives easier, we should organize our code into coherent chunks.

This way, we can find the code later.

Use HTTP/2

HTTP/2 is the latest version of JavaScript and provides many enhancements over the original version.

We’ll see speed improvements if we switch to HTTP/2 server for hosting our site.

Performance Optimization Techniques

Performance is an integral part of the Application design and plays a vital role in the success of your product/application. This is Part-2 of the performance optimization articles series. Performance optimization considerations for an enterprise-level application are discussed as part of Part-1.

Before delving into performance optimization techniques, let us discuss the factors that impact the performance of an application. Below are the most critical factors that impact the performance from my view.

Factors That Impact the Performance of the Application

• Stuffing home/start page with lots of functionality
• Making a huge number of API calls/ Loading large JS bundles as part of the initial load of the applications
• Ineffective JavaScript modules loading strategies (Not effectively using lazy loading)
• Using large size images without any image optimization/compression
• Preloading all the data in the browser instead of considering user preferences/user actions
• Not adopting CDN to deliver the content to the global audience (at least static content/files)
• Invalid network/tool configurations
• Using the same website/ APIs for Mobile and Desktop
• Introducing additional tools only in the production environment

Performance Optimization Techniques

This section gives you an overview of the various techniques that can be employed at various levels of your application. At a global level, below are few areas

User Interface

Below are a few of the core best practices to consider as part of the user interface design and development

User Interface Design Best Practices

• Consider server-side rendering for your home/landing page if it stuffed with too much functionality
• Load data on demand always
• Enabling paging when dealing with large datasets

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
