Let’s get this out of the way upfront. Node.js is an open-source JavaScript runtime environment that enables JavaScript code to be executed outside of a web browser.

There’s a lot to unpack there. Let’s do just that. First, we’ll answer the question.

A Bit of History

Thirteen years after the first server-side country email list JavaScript environment (LiveWire Pro Web) was released, Ryan Dahl created Node.js. Why was this even necessary?

Dahl held a number of criticisms for LiveWire Pro Web. Back in those early days, Apache had trouble handling a large number of concurrent connections and the wide-spread use of sequential programming could lead to blocking an entire process or required multiple execution stacks.

The Advantages of node.js

Node.js offers quite a lot of advantages sem: what it is, types, and everything you need to know and has become crucial for a number of modern, agile technologies. Let’s take a look at some of the advantages.

Node.js is scalable

Wait. What? What’s horizontal and vertical scaling? Let’s define.

• Vertical scaling (aka “scaling up”) is mobile list adding more resources to a server without changing code.
• Horizontal scaling (aka “scaling out”) is adding more machines to a network to share processing and memory workloads.

You can add extra resources to the hardware or more hardware to the network and Node.js won’t flinch.
