I’m going to have to go down the rabbit hole of making my own website soon. Just curious but would there be an easy way to show a pop up just to people using chrome?
No reason in particular… 😏
lol i did something like what i assume your goal is on my neocities when i detect
!!window.chrome === true
Why the double negation?
It's a handy way to convert any value to a Boolean. If
window.chromeis defined and done non-empty value, double negation turns it into justtrue.I've been wondering why not
window.chrome == trueorBoolean(window.chrome), but it turns out that the former doesn't work and that==has essentially no use unless you remember some completely arbitrary rules, and that JS developers would complain that the latter is too long given the fact that I've seen javascript code using!0for true and!1for false, instead of justtrueandfalsebecause they can save 2 to 3 characters that way.==has essentially no use unless you remember some completely arbitrary rulesIf you make sure the types match, like by explicitly converting things on the same line on that example, then you can use it just like if it was
===.In fact, there are people that defend that if your code behaves differently when you switch those two operators, your code is wrong. (Personally, I defend that JS it a pile of dogshit, and you should avoid going to dig there.)
I've never seen the
!0and!1, it is dumb and indicates either young or terrible devs.Boolean(window.chrome)is the best,!!window.chromeis good, no need to test if it's equal totrueif you make it a boolean beforehand.i just added the
=== truefor clarity
JS "idiomatic" way to cast to boolean. But could just be written as
!window.chromeinstead.
Not sure if serious, but there's a million ways to do this, some that require importing thousands of lines of code and none of which are guaranteed to work in all possible circumstances. But here's a simple one.
Im stupid Stones but I think it's in the user agent information, browser and version and other shit
User agents cannot be fully trusted anymore since every browser puts every possible word in it so they are not excluded by anything.
Well, some browsers have made User-Agent strings useless. Technically, it's like this:
Firefox: "Mozilla based browser, Gecko engine, Firefox."
Chromium: "We're totally a Mozilla based browser we swear. Also KHTML, which is like Gecko basically. I guess also a bit like WebKit. Has anyone ever heard of those? No? OK. Fine, here's some actual information then..."
