Script Preparation code:

  function a(ArrayLike, map, thisArg) {
      return 'length' in ArrayLike ? map ? [].map.call(ArrayLike, map, thisArg) : [].slice.call(ArrayLike) : map ? Array.from(ArrayLike, map, thisArg) : [...ArrayLike]
  }
let b = Array.from
let c = Array.of.apply.bind(Array.of,1)
let arr = Array.from({length:1e3},(a,i)=>i),
    set = new Set(arr),
    generic = {length: 1e3}

Tests:

Array.from
b(arr) b(set) b(generic)
native from
a(arr) a(set) a(generic)
Array.of
c(arr) c(set) c(generic)
