what kind of and How to use object methods in js?

Answer 1

as you r saying they are objects methods , they can be used in the same manner as in other languages
I.e objectName.methodName

for eg.

var student = {

' Name ' : ' Kunal'
' Address' : 'ndnnd'
' getMarks' = function { }
};

u'll access this as

student.getMarks ().
