Is nodejs a language?

nodejs is not a language, but an open source, cross-platform execution environment that can run JavaScript on the server side; Node uses the V8 execution code developed by Google, using event-driven, non-blocking and asynchronous input and output models and other technologies to improve performance and optimize application transfer volume and scale.

Is nodejs a language?

nodejs is not a language.

Node.js is an open source, cross-platform execution environment that can run JavaScript on the server side. Node.js is owned and maintained by the OpenJS Foundation (formerly the Node.js Foundation, which merged with the JS Foundation) and is a project of the Linux Foundation.

Node.js adopts the V8 execution code developed by Google and uses technologies such as event-driven, non-blocking and asynchronous input and output models to improve performance and optimize the transmission volume and scale of applications. These techniques are typically used in data-intensive real-time applications.

Node.js Most of the basic modules are written in JavaScript language. Before the emergence of Node.js, JavaScript was usually used as a client-side programming language, and programs written in JavaScript were often executed on the user's browser. The emergence of Node.js enables JavaScript to be used for server-side programming. Node.js contains a series of built-in modules that allow the program to be executed as an independent server without Apache HTTP Server or IIS.

Currently, Node.js has been adopted by IBM, Microsoft, Yahoo!, Walmart, Groupon, SAP, LinkedIn, Rakuten, PayPal, Voxer, GoDaddy and other companies.

Node.js uses the Google V8 JavaScript engine because:

• V8 is open source software based on the BSD license

• V8 is very fast

• V8 focuses on network functions and is more mature in HTTP, DNS, TCP, etc. Compiled from source code

We can use the following command to view the current Node version:

$ node -v
v4.4.3

Note: There may be differences between different versions.
