An Introduction to Full Stack Development with JavaScript

What exactly does the term "full stack" in web development mean?

Simply put, picture a website as having two layers: a backend layer and a frontend layer. When combined, these layers form a technological stack.

Originally, JavaScript was solely a web client language. Then, however, Node.js made it possible for JavaScript to be used on the web server, enabling full-stack JavaScript development.

With full stack JS, JavaScript and JavaScript tools are used to create every component of the online application, including the client and server sides. Companies are currently hiring full stack developers like crazy.

What is Full Stack JavaScript Development?

Full stack refers to all the components that make up a web application, including the technology that powers it, the database, the user interface, and the front-end business logic.

A full stack JavaScript developer is capable of using JavaScript to deal with both frontend and backend code to create a web application. They are equally adept at building databases and APIs as they are at building the user interface.

Companies That Hire Full Stack Developers

Currently, full stack JavaScript is extremely popular. Several businesses employ full stack software engineers, making use of the JavaScript convention. To name a few:

• Facebook
• Pinterest
• Apple
• Netflix
• Amazon (AWS)
• AirBnB
• Geomotiv
• TeleHealth industries
• JPMorgan Chase Bank
• Most start up companies

Pros and Cons

The use of JavaScript throughout the entire stack of the application has both advantages and disadvantages. Here are a few to consider when deciding if a JavaScript tech stack is appropriate for you or your company.

Pros

• No need to reevaluate the reasoning in a different language that can increase the time required to finish a task. The writing of the code is made slightly easier by similar ideas. Teams function more effectively when everyone is familiar with the codebase.
• Since both the client and the server are written in JavaScript, there is a lower likelihood of coding problems caused by incorrect syntax. The codebase of your project is abstracted away by using npm's node modules in both the front- and backend.
• Due to its performance, asynchronous JavaScript makes use of the event loop, making it a highly sought-after technology. Today's big tech businesses love it since it's lightweight and quick.
• Along with Python and Java, JavaScript is among the most widely used programming languages worldwide. Finding a new developer to join the team or learning the coding doesn't take too much time.
• There are many resources available in the large community of JavaScript web developers.
• You can see from the NPM homepage that we have a huge selection of open-source applications and modules at our disposal for use in projects. The cost-to-market for your product is reduced as a result.

Cons

• Node.js is not the best choice if your project calls for intensive mathematical computation or sophisticated algorithms. Use a backend system that is better suited to handling that kind of dataset if you want to get the best results.
• Relative to PostgreSQL or MySQL, Node.js is a comparatively recent piece of software. Being young might occasionally imply lacking knowledge of how to tackle challenges.

Conclusion

Now that you know what a full stack web developer does, you can decide if you want to become one. A whole stack strategy should be taken into consideration while you create your web pages. Your current skill level will determine what you should learn next.

Learn JavaScript first if you are just starting out in web development. If you are familiar with the language, you might choose to take on a framework or library.
