JavaScript Default operator

26Jun10
this.init(wrapper, handle, options || {});

ใน input parameters ของ function สามารถเขียนแบบนี้ได้ เรียกว่าการใช้ trusty กับ falsy

var A = 0, B = NaN, C = 1, D = "hi";
var RESULT = ( A || B || C || D );
alert("Result = " + RESULT);

RESULT = ( D && C && B && A );
alert("Result = " + RESULT);

ถ้าเอามาต่อกันด้วย or operator จะหาอันที่เป็น true จากซ้ายไปขวาอันไหนที่ให้เป็น true อันแรกก็จะเป็นค่านั้น
แต่ถ้าเอามาต่อด้วย and operator จะหาอันที่เป็น false อันแรกจากซ้ายไปขวา ถ้าเจอ false อันไหนก็เป็นค่านั้น
