Using typeof in JavaScript

//typeof() will return the type of value in it's parameters.
//some examples of types: undefined, NaN, number, string, object, array

//example of a practical usage
if (typeof(value) !== "undefined") {//asuming value is already set
  	//execute code
}

console.log(typeof 'blubber');

typeof("iAmAString");//This should return 'string'
//NO camelCase, as it is a JS Keyword
