yeah but why is a single character string containing a tab equal to zero ???
That would be weird if a string containing a space wasn't equal to 0
" " == 0, but that's not the case in JS. If you think that""and" "being equal to 0 is weird then I agree, but since they are, you should expect"\t"and"\n"to equal 0 too.The
==operator in JS will try to cast the things being compared and do all kinds of 'smart' assumptions about what equality means. This is why everyone uses===instead...Unless you enjoy inviting the chaos.
