You are creating a function by using JavaScript. The function accepts an object as the parameter and
returns a string that identifies the data type of the object.
You have the following requirements:
The function must return “Number” if the object is a number.
The function must return “String” if the object is a string.
The function must return “Unknown” if the object is neither a number nor a string.
You need to implement the function to meet the requirements.
