how to apply Math.min on a array who have a null value inside?

[espace 25]

Hi, 

I would like to know the lowest value on my array. So i make 

var arr=[0,1,2,3]

console.log(Math.min(...arr)) => 0 ok

The problem is that my array contains this :

var arr=[null,0,2]
var min=Math.min(...arr)
arr.indexOf(min) => -1 because it take null as lowest value...how to eject the null value ?

How do you eject the null value from the Math.min() ?

@espace Your code returns the correct "1" for me (Chrome v77 desktop).  Perhaps this is implemented inconsistently across engines?

If so try filtering the array and removing the nulls before the Math.min:

var min=Math.min(...arr.filter(v=>v!=null))

A more optimal solution might be needed if your array is large?
