javascript - what is the difference between '!= 'and '!== ' -


possible duplicates:
is there difference between !== , != in php?
javascript === vs == : matter “equal” operator use?

in cases when checking not equal, saw using != , in places saw !==. there difference in that?

example:

var x = 10;     if (x != 10) {        //... }

and 

if (x !== 10) {         //... }

== compares value , converts between types find equality, === compares types well.
