Is nodejs c?

Node.js is a JavaScript running environment based on the Chrome V8 engine. It allows JavaScript to run on the server side, greatly expanding the application scope of JavaScript. But Node.js is not a C language, but written in C.

C language and C language are two different programming languages. Although C can be compatible with C language, they still have many differences. C language is a low-level programming language that is closer to the hardware and directly operates the memory and CPU of the computer system; while C language adds object-oriented programming features to the C language. Node.js is written in C, and the calls to the underlying API and the use of the V8 engine are all implemented through C code.

So why does Node.js use C? This is mainly because Node.js needs to handle large amounts of requests and data efficiently. Code written in C can manage memory and resources more efficiently and provide better control over the operation of the computer system. At the same time, C also provides a wealth of APIs and libraries, which can help Node.js interact with other systems more conveniently.

Node.js uses the V8 engine to parse and execute JavaScript code. The V8 engine is an open source JavaScript engine developed by Google. It is written in C rather than implemented in JavaScript. This is why Node.js requires C. Node.js modules written in C are usually C bindings for V8. These modules interact directly with the V8 engine and provide the APIs required by Node.js.

In short, Node.js is written in C, but it is not a C language. Code written in C can help Node.js handle large amounts of requests and data more efficiently, and JavaScript can be easily run on the server side using the V8 engine.
