javascript switch/case : are types compared? -

-

possible duplicate:
is safe assume strict comparison in javascript switch statement?

does switch/case statement in javascript compare types or values?

in other words, when have following code:

switch (variable) {     case "0": [...] break;     case "1": [...] break;     default: [...] break; }

is equivalent to

if ( variable == "0" ) {     [...] } else if ( variable == "1" ) {     [...] } else {     [...] }

or to

if ( variable === "0" ) {     [...] } else if ( variable === "1" ) {     [...] } else {     [...] }

edit: there way force compare values , types @ once?

yes, types compared.

if input equal clauseselector defined === operator, set found true.
