You may know that HTML, CSS, and JavaScript are at the heart of frontend development. You can make web pages dynamic, interactive, and optimized for all kinds of devices quickly and efficiently using JavaScript.
Any data can be fetched from the webserver or API and make visible without reloading the page. That’s the beauty of JavaScript.
Maybe you are currently using JavaScript for front-end development. Add custom animation to the page elements to make web pages look cool. Use Ajax to send and retrieve data from a server asynchronously without interfering with the existing page’s display and behavior. These usages of JavaScript are common for front end web development. There’s a lot you can do using JavaScript.
JavaScript is not limited to client-side development. You can use JavaScript for machine learning, deep learning too. But can it be used for backend web development?
Today I will discuss if we can use JavaScript for backend development. Without further talking, I will directly move on to the topic.
What is Backend development?
If you know about static web pages or sites and how they work, it will be easy for you to understand what is backend development. In static web pages or sites, contents don’t change much. A static web page is right for the business, project showcase, or restaurant.
But what if you need to show or store data or information to users individually or perform actions or operations for different users and show the output? In this case, backend development comes to solve this issue.
The backend is the portion of the website you don’t see. It’s responsible for storing, organizing, and ensuring everything works fine on the client-side works. The backend communicates with the frontend to send and receive information.
For example, if you try to login into your account, you must fill in username/email and password. After that, when you click the login button, the login request is sent to the server.
The server will respond if the username or password is valid or not. Then you will be able to login if login credentials are valid or can see an error message if not correct.
Now, let’s talk about whether we can use JavaScript for backend development or not.
Can you use JavaScript Backend development?
Nowadays, you can also use JavaScript for backend development. You can simply use Node.JS.
There are lots of JavaScript frameworks for backend development. ExpressJS, NextJS, MeteorJS, Koa, NuxtJS, Fastify e.t.c are the popular frameworks. You can choose any of these frameworks. But It will be better if you learn more about them before selecting them.
If you want to learn JavaScript for backend development, I would tell you to go for it because it’s good to know new technologies. But it’s your choice whether you want to use it to complete your work or not.
Conclusion
Now you know you can use JavaScript for both frontend and backend development. There are lots of JavaScript frameworks and libraries for clientside and serverside development. But it’s not so easy to choose the right one.
So, before making any decision, you should know about their features and other benefits they provide and whether you will be able to solve your problem or not.
