56bbb991ad1ed5201cd392d2 | Add New Properties to a JavaScript Object | 1 | https://scrimba.com/c/cQe38UD | 301169 | add-new-properties-to-a-javascript-object |
--description--
You can add new properties to existing JavaScript objects the same way you would modify them.
Here's how we would add a bark
property to ourDog
:
ourDog.bark = "bow-wow";
or
ourDog["bark"] = "bow-wow";
Now when we evaluate ourDog.bark
, we'll get his bark, bow-wow
.
Example:
var ourDog = {
"name": "Camper",
"legs": 4,
"tails": 1,
"friends": ["everything!"]
};
ourDog.bark = "bow-wow";
--instructions--
Add a bark
property to myDog
and set it to a dog sound, such as "woof". You may use either dot or bracket notation.
--hints--
You should add the property bark
to myDog
.
assert(myDog.bark !== undefined);
You should not add bark
to the initialization of myDog
.
assert(!/bark[^\n]:/.test(code));
--seed--
--after-user-code--
(function(z){return z;})(myDog);
--seed-contents--
var myDog = {
"name": "Happy Coder",
"legs": 4,
"tails": 1,
"friends": ["freeCodeCamp Campers"]
};
--solutions--
var myDog = {
"name": "Happy Coder",
"legs": 4,
"tails": 1,
"friends": ["freeCodeCamp Campers"]
};
myDog.bark = "Woof Woof";
