java - node.js关于模块的问题

Question

作为一个从java转过来的码农来说，我想知道node.js对于各种模块应该也有类似于java那种类的api吧！可是我却找不到，还有我想知道java的类和node.js的模块有什么区别？有什么相同点和不同点？

Answer 1

It just so happens that I also worked in Java before (although I haven’t used it deeply, but I can talk about it and understand it)

Java platform includes:

1. Java Programming Language

2. Java Class file format

3. Java Application Programming Interface (API)

4. Virtual Machine (HotSpot, etc.)

Corresponds to the node platform:

1. ECMAScript

2. (none)

3. node platform API

4. Javascript Engine (V8)

Comparison of other concepts:

• Java package - node module

• Java maven - node npm

• Java class - ES6 Class (ES5 simulation class)

Answer 2

The two APIs are not at the same level and are not comparable.

• JDK’s built-in API has thousands of classes

• The built-in API of nodejs only has dozens of classes and functions.

nodejs only provides the most basic API, most functions require third-party libraries to implement
