minus-square@marcoslink7•10 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-210 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•10 months agoNot a JS dev either but ===. Not really sure what the (+x) is about
minus-square@[email protected]linkfedilink1•10 months agothe remainder operator should return a number or a NaN right? do we actually need the triple here?
minus-square@marcoslink2•edit-210 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.
