if (cell.hasOwnProperty('Relationships')) {
console.log("Key Found!!");

console.log("Not Found.");
}

if (cell.hasOwnProperty('Relationships')) {
console.log("Key Found!!");
}
else {
console.log("Not Found.");

!"key" in obj // ERROR! Equivalent to "false in obj"
JSON.stringify(JSONObject).includes("dog")
