Boolean 3/4
The Boolean() Function:
The Boolean() function, in JavaScript, is used to return or convert a value to its Boolean value i.e., true or false.
Almost any value is evaluated as true if it has some sort of content, for example.
12let name="paul"; console.log(Boolean(name));
As you can see for the above variable, name we get the output as true because it had a string value. An empty string would have given a false output.

Use the Boolean method to check wheater the value given to the variable emptyString is true or false. Show the answer on the console.
Soluzione
