minus-squareinvalidusernamelol [he/him]hexbear14·edit-23 years agoMy favorite thing about JS is that it has true and false evaluations that are more guidelines than rules Pop quiz: Which is true and which is false? a) "false" == true b) "0" == true c) [] == true d) " " == true (They're all true) link
minus-squareinvalidusernamelol [he/him]hexbear10·edit-23 years agoI still think JS is an incredibly useful language, but god damn is the concept of "truthy" and "falsey" just insane. link
minus-squareMoreLikeSexbearLmao [he/him]hexbear7·3 years agoI disagree, I think python handles it pretty well. JS just has some pretty bad rules for truthiness. In python: numbers are truthy if they're non-zero containers and strings are truthy if they are non-empty a regex result is truthy if it matched something the None object is not truthy custom objects are truthy by default, but you can define the thruthiness function link

Pop quiz:
Which is true and which is false?
a)
"false" == trueb)
"0" == truec)
[] == trued)
" " == true(They're all true)
That is horrifying.

In python:
numbers are truthy if they're non-zero
containers and strings are truthy if they are non-empty
a regex result is truthy if it matched something
the None object is not truthy
custom objects are truthy by default, but you can define the thruthiness function
