Basic JavaScript - Testing Objects for Properties

JavaScript
1

function checkObj(obj, checkProp) {
// Only change code below this line
return “Change Me!”;
// Only change code above this line
}

Modify the function checkObj to test if an object passed to the function (obj ) contains a specific property (checkProp ). If the property is found, return that property’s value. If not, return "Not Found" .

I could not find the answers to the questions. can you help?

first you need to check if the object passed to the function has specific property (checkProp). You can use obj.hasOwnProperty(checkProp), if its true return obj[checkProp] and return “Not Found” if its false.

Have you tried a code analysis tool? For example AppRefactoring

How would that be even remotely helpful?

I think there will be something like return obj[checkProp] ? obj[checkProp] : "Not found".

Please do not try to give solution code.
