Helper to determine the minimum of an array

Example 1:

const a = [1,2,3,4]
// default behavior:
minOfArray(a,"") // => 1
// if no data present at the path the default value is used:
minOfArray(a,"a",1) // => 1

Example 2:

const a = [{value:1},{value:2},{value:3},{value:4}]
// default behavior:
minOfArray(a,"value") // => 1
// if no data present at the path the default value is used:
minOfArray(a,"a",1) // => 1
