Set spread
const f = [... new Set(array)]
const f = [... new Set(array)]
Array from set
const s = new Set(array) const l = Array.from(s)
const s = new Set(array)
const l = Array.from(s)

Filter

const b = array.filter((i,index) => array.indexOf(i)=== index)

 
const b = array.filter((i,index) => array.indexOf(i)=== index)
