A Full Stack JavaScript Developer is a software developer who uses JavaScript to work on both the front-end (client-side) and back-end (server-side) of web applications. This means they have the skills to manage the entire development process, from designing the user interface to handling server logic and databases. Here's what they typically work on:
1. Front-End Development:
- HTML/CSS: Uses HTML for structure and CSS for styling to create the visual layout of a website.
- JavaScript: Enhances interactivity and functionality on the client side, such as animations, form validation, and dynamic content loading.
- Front-End Frameworks/Libraries: Commonly uses frameworks or libraries like React, Angular, or Vue.js to build modern, responsive user interfaces. These tools help manage the complexity of front-end development and improve performance.
2. Back-End Development:
- Node.js: Uses Node.js, a JavaScript runtime, to write server-side code. This allows them to handle requests, manage databases, and perform other server-side operations using JavaScript.
- Express.js: Often uses Express.js, a popular framework for Node.js, to build web applications and APIs. It provides a robust set of features for web and mobile applications.
- Databases: Works with databases like MongoDB, MySQL, or PostgreSQL to store and retrieve data. They use JavaScript to interact with the database, often through an Object-Relational Mapping (ORM) tool or directly using database queries.
3. Full Stack Integration:
- They ensure seamless communication between the front-end and back-end, making sure data flows correctly between the client and server.
- They may also work on setting up and managing servers, deploying applications, and handling other aspects of full-stack development, such as security, scalability, and performance optimization.
A Full Stack JavaScript Developer is essentially capable of building a complete web application from scratch, using JavaScript across the entire stack.
