<article> tag allows to mark separate entries in an online publication, such as a blog or a magazine. It is expected that when articles are marked with the <article> tag, this will make the HTML code cleaner because it will reduce the need to use <div> tags. Also, probably search engines will put more weight on the text inside the <article> tag as compared to the contents on the other parts of the page.

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.

* Use the switch statement to select one of many blocks of code to be executed.
Syntax switch(expression) {
case n:
code block break;
case n:
code block break;
default:
default code block
}
This is how it works:
The switch expression is evaluated once.
The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed.
* Object.prototype.constructor
Returns a reference to the Object function that created the instance's prototype. Note that the value of this property is a reference to the function itself, not a string containing the function's name. The value is only read-only for primitive values such as 1, true and "test".
* Description
All objects inherit a constructor property from their prototype: var o = {};
o.constructor === Object; // true var a = [];
a.constructor === Array; // true var n = new Number(3); n.constructor === Number; // true
* The constructor property is created together with the function as a single property of func.prototype.
