Checks if the target value exists in a JSON object.

• Use Object.values() to get all the values of the object.
• Use Array.prototype.includes() to check if the target value is included in the values array.

const hasValue = (obj, value) => Object.values(obj).includes(value);

const obj = { a: 100, b: 200 };
hasValue(obj, 100); // true
hasValue(obj, 999); // false
