Benchmark: set vs array membership

Script Preparation code:

const shortArray = [1,9,5,3,8,7,2,1,4,1]
const shortSet = new Set(shortArray)

const mediumArray = Array.from({length: 100}, (x,i)=>i)
const mediumSet = new Set(mediumArray)

const longArray = Array.from({length: 4000}, (x,i)=>i)
const longSet = new Set(longArray)

Tests:

short Array.includes
return shortArray.includes(7)
short Set.has
return shortSet.has(7)
medium Array.includes
return mediumArray.includes(62)
medium Set.has
return mediumSet.has(62)
long Array.includes
return longArray.includes(2917)
long Set.has
return longSet.includes(2917)
