Node.js uses the V8 JavaScript runtime engine as its root power, and it employs a non-blocking I/O architecture that’s event-driven. As a result, you can ultimately build and run a program using only JavaScript with Node.js. The Node.js environment empowers JavaScript to directly employ the database and function properly as a backend language.

Consequently, you had to learn server-side languages like PHP, Python, Ruby, or C# - or seek a backend developer’s help. That’s because JavaScript couldn’t regulate the backend process. Most conventional websites and API services today depend on Node.js.īefore Node.js, if you wanted to store any data on the database or connect your program to the database, you needed support from a server-side language. But since then, Node.js has grown into a vital element for server-side programming for event-driven, non-blocking servers. Initially, Node.js was designed to serve real-time performance, pushed-back architectures. As a result, you can use JavaScript for frontend and backend development, enabling full-stack development solely using JavaScript. Node.js is an open-source runtime environment for the JavaScript language that reshapes JavaScript’s characteristics and upgrades its functionality. You may already be aware of this fact, but it bears repeating for new developers in the field who may mistake Node.js for a unique programming language. The first thing you should know is that Node.js is not a programming language!
