What you can expect during Node JS training?
A Node.js training involves gaining hands-on experience in developing applications using the Node.js runtime environment and JavaScript. Node.js is a popular open-source platform that allows developers to build server-side applications and APIs using JavaScript. Here’s a general description of what a Node.js training might entail:
Position Title: Node.js Development Trainee
Duration: Typically ranges from a few weeks to a few months, depending on the company’s program.
Objective: To provide trainee with practical experience in developing server-side applications and APIs using Node.js, allowing them to apply theoretical knowledge and learn new skills in a professional setting.
Roles and Responsibilities:
Backend Development: Assist in designing and building server-side logic, APIs, and databases using Node.js.
API Development: Collaborate with the team to create RESTful APIs or GraphQL endpoints to enable communication between the frontend and backend.
Database Integration: Work with databases such as MongoDB, MySQL, or PostgreSQL to store and retrieve data in applications.
Application Logic: Participate in writing server-side logic to handle requests, process data, and implement business logic.
Authentication and Authorization: Implement user authentication and authorization mechanisms to ensure secure access to resources.
Error Handling and Debugging: Assist in identifying and resolving issues in the code, including error handling and debugging.
Testing and Quality Assurance: Contribute to writing unit tests and performing quality assurance to ensure the reliability and stability of applications.
Collaboration: Work closely with frontend developers, designers, and other team members to create cohesive applications.
Version Control: Use version control systems like Git to collaborate on code and manage codebase changes.
Continuous Integration/Continuous Deployment (CI/CD): Learn about and potentially assist in setting up CI/CD pipelines to automate deployment and testing processes.

FAQ
Node.js is an open-source runtime environment built on Chrome's V8 JavaScript engine. It allows developers to execute JavaScript code on the server-side, enabling them to build scalable and high-performance applications.
The candidate must have the basic understanding of computer and internet works. And good to have the basic knowledge of HTML , CSS and JavaScript concepts.
You can create a new Node.js application by creating a project folder, navigating to that folder in the terminal, and running npm init to set up a package.json file. This file will store metadata about your project and its dependencies.
A callback is a function that is passed as an argument to another function and is intended to be executed later, usually once a certain task has been completed. Callbacks are commonly used in asynchronous programming in Node.js.
Promises are a way to handle asynchronous operations in a more readable and organized manner. They represent a value that might be available now, or in the future, or never.
Asynchronous programming in Node.js allows tasks to run independently without blocking the main thread. This is crucial for handling I/O operations, network requests, and other non-blocking tasks efficiently.
The Event Loop is a fundamental concept in Node.js that enables the execution of asynchronous code. It continuously checks the call stack and the task queue to execute functions in a non-blocking manner.
Node.js provides several built-in core modules such as fs (file system), http (HTTP server and client), path (path-related operations), util (utility functions), and more, which help in building applications without external dependencies.
Environment variables can be managed using the process.env object in Node.js. You can set environment variables in your shell, in configuration files, or using tools like dotenv to manage them more easily.
