undefined is a property of the global object, i.e. it is a variable in global scope. The initial value of undefined is the primitive value undefined. In modern browsers (JavaScript 1.8.5 / Firefox 4+), undefined is a non-configurable, non-writable property per the ECMAScript 5 specification. Even when this is not the case, avoid overriding it.
To put matters straight: Division is a function q:RÃRâ,(a,b)â¦q(a,b)=:ab , whereby q(a,b) is the unique number xâR such that bx=a. When we say that a0 is undefined then this means no more and no less than that the pair (a,0) is not in the domain of the function q(â,â). Now to your three ways of understanding undefined in the realm of division by 0: If a0 could be any number, say =13, then this would enforce 13â0=a, which is wrong when aâ 0.
