Finding the maximum property under a value
I have a list of objects, each with its properties.
I am trying to find a specific object in this list with this .find although I can't figure out how to find the maximum value of one of it's properties under a certain value.
let x = this.state.pricing_adjustments_view.filter((e) => {
return e.location_id === this.state.selectedLocation,
e.car_model_id === this.state.selectedCar,
moment(e.calendar_day).isSame(this.state.from, "day"),
_.max(e.minimum_duration) <= duration
})
Here it's the e.minimum_duration. I want to find the biggest value, but that is under "duration"
I am trying it with "lodash", here represented by the "_".
I am open to other possibilities.
this.state.pricing_adjustments_view is an array of objects, and you could say that for each object, the "UNIQUE" key is its "location_id", "car_model_id", "calendar_day" and "minimum_duration".
So there are several objects that are the same if we only consider "location_id", "car_model_id", "calendar_day", and then they have different "minimum_duration". I need to get the one that has the highest "minimum_duration".

return with a check and comma operator? either some code is missing or it makes no sense.

@NinaScholz it's how i usually do it, .filter((e) => {return e.thing = thing, e.thing = thing}) and it works

I'm not certain there is enough detail here for us to help you, consider reading up on Minimal, Complete, Verifieable Example

for examplee.location_id === this.state.selectedLocationhas nothing to do with the rest. it is not use in anifclause, nor as expression as return value or as part of a ternary.
