Root82483140dI don’t think so.
Zero should, but negatives are “present” (to use a Rubyism) so they would be truthy. -
jestdotty5053140dno but you can make -1 (which is returned when you try to find something in an array and it isn't in the array) be false using ~
false is on 0, positive and negative numbers have bits in them therefore will evaluate to true -
Lensflare16929139dI bet there are countless js devs who write code which relies on this and they think that they are super clever 10x devs.

Parzi8833139dI'm pretty sure the true/false comparison compares to 0 exactly. Python does the same thing, and it lets you get up to some useful signaling bullshit (return either False or an object, easier to check for than NoneType because you can "if not var:" and NoneType is still an object so this check will fail)

I swear negative numbers used to evaluate as false in Javascript?!
