Best way to prevent/handle divide by 0 in javascript

Question

What is the best way to prevent divide by 0 in javascript that is accepting user inputs. If there is no particular way to achieve this what would be the best way to handle s

Answer 1

A bit different than stopping execution, but the ternary operator is a pretty slick way to customize variable assignment.

var one = 1,
    zero = 0,
    customValue = 1;


var quotient = zero===0 ? customValue : one / zero;

This way, by setting the customVariable to the integer of your choice, you can expect a predictable result when division by zero occurs.
