An object used to Add reusable functionality to another object or class, without using inheritance.Simply, adding functionalities to the target prototype!We can add the dogFunctionality mixin to the Dog prototype with the Object.assign method. We can add animalFunctionality to the dogFunctionality prototype, using Object.assign. In this case, the target object is dogFunctionality.class Dog { co..

실제로 요청과 응답 사이에 위치하는 미들웨어 기능 체인으로,하나 이상의 미들웨어 함수를 통해 요청 객체부터 응답까지 추적하고 수정할 수 있습니다. const app = require("express")(); const html = require("./data"); app.use( "/", (req, res, next) => { req.headers["test-header"] = 1234; next(); }, (req, res, next) => { console.log(`Request has test header: ${!!req.headers["test-header"]}`); next(); } ); app.get("/", (req, re..
