Wtf is going on JS...
edit: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/min
Its the min value of the input params, or Infinity.
Why would they even define this value?
Note: I’m not a js dev, do most functions have length?
I am also not a JS dev, we possibly aren't brain damaged enough to understand the perfection.
Most people don't use JS because they think it's perfect... they use it because it's the language that works on web browsers... or because thier coworkers made something in it... or because the library that does what they want uses it...
For such a terrible language, it really has staying power...
JS is the machine code of the web. Fewer and fewer people might write it directly, but it will live as long as the web platform does.
Until some browser can make pages with Python, maybe.
Only if that browser somehow becomes overwhelmingly popular in a market segment BEFORE it gets JS support.
Could make a transpiler for python -> js, and serve python to the browser with a fallback to js if the python isn't supported by the browser
I develop with JS? All I can say is I need more brain damage to understand where is out
Just keep developing with it, you'll get CTE soon.
All functions built with
function name(args) { body }syntax have a length based on the form ofargs. Other ways to create functions might set length (I'm not sure). Most of the functions provided by the runtime environment do have a length, usually based on the number of "required" arguments.And the reason it's Infinity If there is no input, for better or worse, under the hood the method is assigning a variable, min, the highest value possible and then comparing it to each element in the list, reassigning it when it encounters an element lower than its value at the time. So it will obviously always be reassigned if there are any elements at all (if they're less than Infinity, I guess). But if there are no elements, it's never reassigned, and thus returns Infinity. It could have just signed min to the first element instead if Infinity, but that would lead to a runtime error when min was run without a function. If you're not going to throw a runtime error though, it makes sense for min to return Infinity because, what other number could you return that couldn't actually be the minimum
