--description--
当你创建了一个对象后,你可以用点操作符或中括号操作符来更新对象的属性。
举个例子,让我们看看ourDog
:
var ourDog = {
"name": "Camper",
"legs": 4,
"tails": 1,
"friends": ["everything!"]
};
让我们更改它的名称为 "Happy Camper",这有两种方式来更新对象的name
属性: ourDog.name = "Happy Camper";
或 ourDog["name"] = "Happy Camper";
现在,ourDog.name
的值就不再是 "Camper",而是 "Happy Camper"。
--instructions--
更新myDog
对象的name
属性,让它的名字从 "Coder" 变成 "Happy Coder"。
--hints--
更新myDog
的"name"
属性, 使其等于 "Happy Coder"。
assert(/happy coder/gi.test(myDog.name));
不要修改myDog
的定义。
assert(/"name": "Coder"/.test(code));
--seed--
--after-user-code--
(function(z){return z;})(myDog);
--seed-contents--
// Setup
var myDog = {
"name": "Coder",
"legs": 4,
"tails": 1,
"friends": ["freeCodeCamp Campers"]
};
// Only change code below this line
--solutions--
var myDog = {
"name": "Coder",
"legs": 4,
"tails": 1,
"friends": ["freeCodeCamp Campers"]
};
myDog.name = "Happy Coder";
