Need some clarification on operator symbol

[mahe]

I have 2 sets of statements

if(current.u_rca.nil() && current.u_rca_attached)

{

current.u_rca_attached = 'false' ;

This code is getting executed in a business rule where the condition is if u_rca_feild is nil and u_rca_attached field which is selected (Check box) on the incident form , the u_rca_attached field will also turn to false (uncheck) once we save the record , so my questions are

a) Can we use current.u_rca_attached === "true" in the above line ?

b) If no , why not ?   I tried using point a in the code but it did not work.

c) so is === operator means equal to or something else ?

d) does it have a different meaning in client script vs business rule ?

Thats my 2 cents here,

===   matches the type as well as value whereas == just matches the value

[Aka Guglielmo]

== and === are pretty similar, they are used in condition statement to check if a value is equal to another one

ie:

if (a==b)

= is used to assign a value to a variable

ie:

var a="hello";
