'===' performs better than '==' because no type conversion is need. Are there any reasons you would use '==' instead of '==='?

  I can think of two. * (programmer) laziness * if you know you want type coercion

    And I just love me some good old fashioned laziness. I mean seriously THREE equals!?

  When you know ahead of time that the types don't need to be coerced: http://jsperf.com/triple-equals-vs-twice-equals/4 http://jsperf.com/triple-equals-vs-twice-equals/4 There's even a negligible performance improvement, at least for me (iPad WebKit Safari).

    For me the "3-equals-true-non-coerced" is the fastest in Chrome 16.
