Today's Moment of Zen
This edition, To Wash It All Away, does not disappoint.
“\r\n\t” == false
WTF? I had to try it out.
% node > "\r\n\t" == false true
And of course, the explanation from James:
Here’s why: the browser detects that the two operands have different types, so it converts false to 0 and retries the comparison. The operands still have different types (string and number), so the browser coerces “\r\n\t” into the number 0, because somehow, a non-zero number of characters is equal to 0. Voila—0 equals 0! AWESOME. That explanation was like the plot to Inception, but the implanted idea was “the correctness of your program has been coerced to false.”
Really, I just had to share.
