Using || and && are NOT yust tricks. [unlees you define programming as pure trickery] compare: var a = f(); var b = g(); var c = a || b; with var c = f() || g(); The two scripts are not equal in Javascript! The positioning of the two funcions is relevant, not as expected in pure calculus. The difference is that if the first function is false [in the case of || ] or true [in the case of && ] the second function is not executed. This has two efficient advantages [1,2] and one avoidable disadvantage [3]: 1 Needless processor-time is spared. 2 Errors in the second function, detected by the first function, ase prevented do collateral damage. 3 Inexperienced programmers planning to use collateral results of the second function, could be bewildered. > Slightly different syntax and semantics between similar languages: ugh! Oh grow up, and do not dwell on your professed extensive experience with other languages, but learn to use the lingo at hand. If languages should be similar, there would be no logical need for using different languages, and we could follow up in Dutch, Greek or Malay. Different languages are needed, because among other reasons: 1 speaker / programmer and listener / engine should understand each other. 2 monoglotism is less fun, gives less insight in languages, lessens developmental change and does not give you this marvelous incentive to use your biological brain. -- Evertjan.
