console.log

印出對象，可以搭配字串，但要小心如果搭配字串可能看不到對象類型

const object1 = {
  a: ["somestring",123], b: 42
};

 console.log(object1);
 // > Object { a: Array ["somestring", 123], b: 42 }
+// 這邊可以看出是個Object
 console.log("object1:"+ object1);
//> "object1:[object Object]"

const data = [
  'a', ["somestring",123],  'b', 42
];

 console.log(data);
//> Array ["a", Array ["somestring", 123], "b", 42]
+// 這邊可以看出是個Array
 console.log("data:"+ object2);
//> "data:a,somestring,123,b,42"
+ // 這邊僅印出array內容

複製內容

一般來說可以在 console 中印出陣列，但 console 會顯示階層式的物件，如果想要複製單純內物件內容，就要透過下列動作達成：

Right-click an object in Chrome’s console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.
