minus-square@[email protected]linkfedilink32•edit-27 months ago is this really a feature not built into Java Script? x % 2 == 0
minus-square@marcoslink27•7 months ago(+x) % 2 == 0 If you forget for a second it’s Javascript, the language will turn back and bite you.
minus-square@[email protected]linkfedilink5•7 months agoI am not good friends with js, what did I miss?
minus-square@marcoslink7•7 months agoThis evaluates to NaN for some reason: '10' % 0 Since JS doesn’t really differentiate strings from numbers, except on the places it does, it makes sense to make sure you are working with numbers.
minus-square@[email protected]linkfedilink2•edit-27 months agoOh right that. I guess I was visualizing a scenario where you already checked for it being a number, such as a Number.isInteger(x) also, that suprises me a lot, you’d think this is one of the places where it treats stuff as numbers
minus-square@[email protected]linkfedilinkEnglish6•7 months agoNot a JS dev either but ===. Not really sure what the (+x) is about
minus-square@[email protected]linkfedilink1•7 months agothe remainder operator should return a number or a NaN right? do we actually need the triple here?
minus-square@marcoslink2•edit-27 months agoNot really. But with JS it’s better safe than sorry. The GP’s addition is unnecessary, but I fully support anyone that decides to do it.
minus-square@ArtVandelaylinkEnglish1•7 months agoAnd so wonderfully similar to the way that symbol is used in other languages as well. Gosh darn it I love JavaScript

(+x) % 2 === 0

point taken!
what does the +x do.
It makes sure
xis a number.what a wonderful and beautiful language. i’m so glad i asked
