Testing Objects for Properties |
Testing Objects for Properties
Here’s the example:
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"
};
function checkObj(checkProp) {
// Your Code Here
return "Change Me!";
}
// Test your code by modifying these values
checkObj("gift");
Here’s a solution:
We do not change anything here:
// Setup
var myObj = {
gift: "pony",
pet: "kitten",
bed: "sleigh"
};
further, in the body of the function we use .hasOwnProperty(propname)
method of objects to determine if that object has the given property name. if/else
statement with Boolean Values will help us in this:
function checkObj(checkProp) {
// Your Code Here
if (myObj.hasOwnProperty(checkProp) == true) {
return myObj[checkProp];
}
else {
and change the value of return
in else
statement:
return "Not Found"
}
}
Now, you can change checkObj
values:
// Test your code by modifying these values
checkObj("gift");
Here’s a full solution:
function checkObj(checkProp) {
// Your Code Here
if (myObj.hasOwnProperty(checkProp) == true) {
return myObj[checkProp];
}
else {
return "Not Found"
}
}
// Test your code by modifying these values
checkObj("gift");
