Asynchronous code - You must be well familiar with asynchronous programming and how it functions before digging into Node.js.

Before learning Node.js, it is advised that you review your JavaScript principles. Knowledge of expressions, loops, data structures, callbacks, functions, objects, this keyword, event handlers, and other related javascript basics is required.

JavaScript - We must have a solid grasp of both the fundamental and more complex principles of JavaScript because the Node.js environment was designed for creating javascript code.

Let us now look at the prerequisites for studying Node.js. Now that you've learned more about Node.js, you should have a clearer idea of how it might enhance your skill set. With appropriate examples, this course will provide you with a thorough grasp of all the necessary components of Node.js.

The goal of this tutorial is to teach software developers the fundamentals of Node.js and its architectural ideas. The V8 engines directly convert Javascript code to faster machine code which the interpreter can run more efficiently. In 2009, Ryan Dahl embedded chrome’s V8 engine (the most powerful and fastest) inside a C++ program and called it Node.įrom a developer’s perspective, Node.js looks asynchronous, event-driven, and single-threaded, although, under the hood, Libuv handles threading and the Event loop. Hence to connect your program to a database or to edit data, you need support from other server-side programming languages like PHP, Python, or Ruby. Node.js package ecosystem that is NPM (node package manager) is the largest ecosystem of the open source libraries in the world.īefore Node, developers were only able to run Javascript inside browsers. Node.js is open-source software (publicly accessible), cross-platform (different operating environment) Javascript runtime environment that runs on chrome’s V8 engine internally.Īs a result, Node.js allows developers to build server-side applications in Javascript developers can execute Javascript code outside the browser. However, it is written with the help of C++, C, and Javascript. Many new developers mistake Nodejs for a programming language like C++ or python.
