Have you ever thought about where and how JavaScript can be used? You might be working on a single project and using JavaScript in just one way, but in truth, there are multiple ways in which you can use JavaScript to make your projects more efficient and wrap up the project quickly. Here in this article, we are going to discuss some of the best use cases of JavaScript, and how it can help developers from different fields.
As a user, you might not know, but the use of JavaScript is everywhere. You can find JavaScript even in the smallest of tech. We can provide you many diverse examples where JavaScript is being used to serve a wide array of purposes. Thus, it is clear to say that JavaScript is a programming language that stands at the forefront of the programming world. If you look at the stats, you will get a better idea of how massive JavaScript is. From all the websites on the Internet, more than 1.6 billion websites use JavaScript in one way or the other. This makes up 95% of the total websites on the Internet.
As a developer or a business owner, you must know how efficiently to utilize such a high-potential programming language. When you are done reading this article, you will have a better understanding of where to use JavaScript in your business and reap its benefits.
Benefits of Using JavaScript
Anyone who wants to learn a new programming language must be aware of the advantages and disadvantages of using it. Each year several new programming languages and frameworks are released. But JavaScript is the one that is loved by programmers. Even students are excited to learn more about JavaScript as it can open many career opportunities for them. The question that might be lurking in your mind is what makes JavaScript so great? Well, the answer lies in this article only. So let’s have a look at the top 10 benefits of JavaScript that you can enjoy while using this programming language in your project.
1. Secure
The first thing you look for in a programming language is how great it is in terms of security. No matter how many features a programming language has, it needs to be secure. If security is an issue, then the programming language can’t be trusted with confidential data. JavaScript has been used for quite some time. However, with each year, there is some new addition to the programming language, which makes it more secure to use. Another benefit of your programming language being secure is that it will allow you to focus on creating the application rather than finding ways to make it compatible with multiple devices and OS.
2. Client-side Language
JavaScript can also be used as a client-side language. By using JavaScript, you can easily make changes on the client-side to make the application perform better and add in the upgrades. Moreover, JavaScript can be used to add up a better interaction between a visitor and the website. There are some websites on the Internet where on clicking any particular button nothing happens in terms of animation, but the desired result is displayed. This type of bad user interface is because the developer didn’t use JavaScript when creating the website.
With the use of JavaScript, you can animate that button to push down when someone clicks on it. In addition to this, there will be more loading and clickable items, and in terms of the user interface, you can make your website more responsive to the actions which the user takes. As a result, it will provide a better experience to your website’s users, and allow them to explore the website for a longer duration.
3. No Dependencies
Independence is something missing when we look at the programming languages, as there are multiple programs that you need to install before you could even write a “Hello World” code. But that’s not the case with JavaScript, you don’t need any program beforehand, and there is no need for any extra installation. In addition to this, even the legacy browser supports JavaScript. As a result, even the old version of Internet Explorer will be able to open a website, which is made in JavaScript, with ease. Moreover, this will help you to rectify your code straight from the web browser, with no need for opening any other application.
You are surely going to find many more reasons which will tell you how JavaScript is independent and can run its show, but the above-discussed points are the most important ones.
4. Easy to Learn
A lot of teachers might have said that Java or JavaScript should not be your first programming language as it is too tough to learn as the first programming language. But that’s not true at all. Starting your computer science learning journey with JavaScript is one of the most streamlined processes and the most beneficial skill to learn in the early stages of your career. The other thing that makes it an excellent programming language for budding computer students is its open-source ability. This makes it easier for a person to attain study material, information, help, and code when they get stuck in their learning.
5. Tons of Frameworks
If you want to create something using JavaScript, you can easily find a framework that provides you with most of the codes to perform a specific task. As a result, you don’t need to write that part of the code as you can easily use the code from the framework. The framework codes are pretty easy to understand.
Thus, their implementation will have no issues at all. Likewise, with frameworks, you get plenty of added features to increase your productivity. This makes JavaScript an excellent programming language for those who know what they are doing when writing the code or developing an application.
6. The Code is Triggered by User Activity
A lot of developers might not know this, but JavaScript programming is based on events. This means when you are writing the code, separate segments of codes are executed in response to a viewer’s action. For example, when a user visits a website and clicks on any button, it will take the user to some other page if the code is written in that way. Also, if the JavaScript code is written to perform some visuals when a user scrolls, then the web page will perform that specific visual.
Moreover, this execution of code implies that not each part of the code gets initialized when the website is being loaded on the browser. This keeps the website’s load time to the minimum for a smoother experience.
7. Multitasking
The world belongs to those who can perform multitasking. The same goes for applications and web pages. But if we look at the technical aspect of multitasking, it has a different name, called concurrency. When using JavaScript, you can include a loop module that can run multiple steps of instructions at the same time. This can help you to handle multiple operations with a single thread.
On the other hand, there are some constraints that a user will feel when they are developing a website using the drag-and-drop functionality of website builders like WordPress, Wix, Weebly, Elementor, etc. They might seem convenient at first, and for the basic websites, they are pretty helpful and can make a great blogging website. But if you are looking for more substantial features and the ability to perform things on your website, you need to use JavaScript as it is a perfect website for creating multi-functional websites that require unique and standout features.
8. You Can Cut Back the Overhead
With JavaScript, you or your employees won’t be spending hours on each project. Also, using JavaScript makes it easier for other team members to understand which project you are working on, and people can easily communicate with each other and discuss the project without any confusion.
Likewise, as a company owner, you won’t be spending money on hiring a tester who will go through the code which your employees have made, as it can be done within a team by some other member. This gives your team more time to think of solutions and features which they want to add to the web application they are developing rather than focusing on the results of the testing and making corrections to them.
9. Dynamic Content
JavaScript can be used to turn your normal-looking website into an interactive web application. With this programming language, you can create popup windows, mouse rollover effects, input validations, and much more. With JavaScript, there’s no limitation to what you can achieve with your application in terms of customizability. With the interactive capabilities, a website will have more user interactions, and users will likely find the website to be more responsive and interesting to stay on and explore the website for a longer time.
10. JavaScript is Still Upgrading
The last benefit of JavaScript is that it is still evolving. Some people will say JavaScript is an old programming language, and now is the time to learn new ones. But if you look around, you will notice that more and more applications are being built using JavaScript. Whether it’s your AAA desktop games, automated controller, or the smart fridge, everything can be controlled by using JavaScript.
We know how massive the mobile development market has become in recent years. The mobile app development is entirely based on JavaScript programming at this moment. If you need to create interactive web applications, you need to use JavaScript programming. Otherwise, your application will not be able to perform at its best, and some of the functions might not ever work at all.
Things to Keep in Mind While Using JavaScript
There are some rules and guidelines that you need to know before you start working on JavaScript as this will make your development process faster and smoother.
Know the Application Context
As we have said earlier, JavaScript can fit in a variety of contexts. The implementation of JavaScript defines how you will be using the application that you have created. Most of the time, the syntax and the frameworks which you will be using will remain the same. So look for the typical pattern when you are developing the app, and in no time, you will be able to realize the context and the frameworks required to create a new application.
JavaScript is Not DOM-Scripting
There was a time when people were using JavaScript to create DOM script web pages, but now the programming language has become more complex and robust too. Yes, it does have some drawbacks as well. For instance, it comes with lousy support for object manipulation and management. But nothing is worse than using such a powerful programming language as DOM scripting. That’s why when writing the code, you need to write it in the proper flow and follow a good design pattern. If you keep on using the language as a DOM scripting, you will never get better at writing the code in JavaScript.
Conclusion
This is what JavaScript usage is all about. It can do anything, and once you learn this programming language, thousands of new opportunities will open up for you. Furthermore, JavaScript is constantly evolving, so in the coming decade, it is going to see a massive change that will increase its adaption and allow developers to create, control, and manipulate more gadgets than before.
If you are thinking, is it the right time to learn JavaScript? Then, without a doubt, we have to say that this is the best time to learn JavaScript and make your career in it.
