what is difference between two object in JavaScript

Question

Can anyone help me to understand the difference in obj1 and obj2 created in two ways in JavaScript? They look the same in the console.

var obj1 = { 'name': 'blue', 'shade': 'dark'};
var obj2 = JSON.parse('{"name":"blue","shade":"dark"}');

because

 (obj1 === obj2)  is false as 
 (obj1 == obj2) is false

while in javascript console show as

Object {name: "blue", shade: "dark"}
Object {name: "blue", shade: "dark"}

Answer 1

尽管对象的内容相同，但是您具有对两个单独对象的引用，这就是为什么==和===都失败（它们检查引用是否为内容）。

Answer 2

As ABucin said, javascript checks for references, if you still want to check if two jsons are equal you could try using

JSON.stringify(obj1) === JSON.stringify(obj2)

or check for every key (a bit more complicated but more efficient in the case that the keys are in different orders).

Try reading this:

Compare 2 json objects

Answer 3

you are creating an object with obj1 and in obj2 you parsing a JSON object into an object. Since both objects are different (different reference) they are treated as different
