const user = { name: "Praveen", videos: ["html", "css", "js"], greet() { console.log(`welcome ${this.name}`); const getVideos = () => { console.log(`You have ${this.videos.length} videos`); }; getVideos(); }, };user.greet();我可以訪問videos.length上面代碼中的值（我使用了箭頭函數(shù)），但我無法訪問videos.length下面代碼中的值：const user = { name: "Praveen", videos: ["html", "css", "js"], greet() { console.log(`welcome ${this.name}`); const getVideos = function () { console.log(`You have ${this.videos.length} videos`); }; getVideos(); }, };user.greet();
JavaScript：箭頭函數(shù)中的 this 關(guān)鍵字訪問問題
