I'm trying to find the minimum y coordinates in an array of points on a graph
some points can share the same X coordinate.
Anything jump out to you smart folk? bc Im' crunching this and it's a beast to me
R.minBy
Brad, I used minBy, but it only takes 2 items at a time, so I had to reduce. I also had to do some insane transforms. Here's my solution:

Am I happy it works? Yes... am I proud of what I did? more than I should be for this turd.
groupBy is a really helpful function in these cases. This utilizes it to separate all the values by their date, and then maps over the object to get the minimum rating
Beautiful code, thanks so much Brad!
I feel like I just leveled up
I don't mean to disparage your solution by the way. I like yours too, just providing an alternative
Is there some cool stepping debugger function for Ramda? Currently I wrote a simple utility function for it:
const sayWhat = message => next => function(){
const outcome = apply(next,arguments)
console.log(message,outcome);
return outcome;
}
@tkvw
tap(console.log)
@xgrommx : nice! does this exists for arguments as well? I quessed
proxy, but is doesn't exists
I need to mitigate the following from returning 'undefined':
const getRole = (roles) => find(
where({ roles: hasSubset(roles) })
);as my pipeline will fail because the next call expects .. something. Is this a good use case for 'Maybe' ?
yes or a
defaultTo
Just curious, is this a good way to ensure the argument is taken as an array?
ifElse(pipe(nthArg(0),type,equals("Array")),nthArg(0),unapply(identity))
@james-gardner What do you want to happen if no item is found?
@tkvw How many arguments are there? what's the shape of your data?
either an array of values, or the values as arguments. So
sum(1,2,3) should work and sum([1,2,3])
That looks like it will work then...
compose(flatten, Array.from)(arguments)
If it can be assumed that none of the array items are arrays themselves then that will work too
I guess it would also require a wrapping function
yours is probably better :)
Thanks, I think this is better
ifElse(Array.isArray,identity,unapply(identity))
