JavaScript-How to use the API

It means I don't know how to use the API. It's always easy to see people using them, but they don't know how to use them.

Easy to understand, API interface is to achieve a certain function of the package, can be encapsulated into function functions, can also be encapsulated into a service, such as the user to order the function, I have created orders encapsulated into the API interface, then the mobile phone app,pc end of the site, all using the next single API interface, can achieve the ability to create orders.
Any interface API has instructions to use the document, such as the Payment API interface, you pass the order ID, amount and other parameters, the interface to help achieve the payment success.

你指的什么API？

你可以把普通页面也理解为Api，这种Api输出的是html代码。

拿一堆参数A，去换另外一堆参数B。
参数A：{"username":chen,"age":20}
参数B：{"status":"ok"}
