JS Common regular: Commonly used JS

--------------------the following common functions
/**
* Format method.
* Eg:
* Two ways of calling
*var template1= "I am {0}, this year {1}";
*var template2= "I am {name}, this year {age}";
*var Result1=template1.format ("Loogn", 22);
*var Result2=template1.format ({name: "Loogn", age:22});
* Two results are "I'm loogn, this is 22."
* @param {} args
* @return {String}
