Why don’t the online compiler not allow the use of “.” as a notation for this question. While it allows the usage of “”
Your code so far
function checkObj(obj, checkProp) {
// Only change code below this line
if (obj.hasOwnProperty(checkProp)) {
return obj[checkProp];
}
else {
return "Not Found";
}
}

I have linked an article which explains the difference between dot and bracket notation in Javascript.
Essentially, it comes down to the difference between static and dynamic keys.
EXAMPLE:
const myObject = {
name: "igorgetmeabrain",
age: 403,
online: true
};
let prop = "online";
// use dot notation to access a static key
console.log(myObject.name); // igorgetmeabrain
// use bracket notation (in quotes) to access a static key
console.log(myObject["age"]; // 403
// using dot notation to access a dynamic key doesn't work
console.log(myObject.prop); // undefined
// using bracket notation (without quotes) to access a dynamic key
console.log(myObject[prop]); // true
