Instructions

Write a bunch of function to move from one type to another

arrToSet from Array to Set
arrToStr from Array to String
setToArr from Set to Array
setToStr from Set to String
strToArr from String to Array
strToSet from String to Set
mapToObj from Map to Object
objToArr from Object to Array
objToMap from Object to Map
arrToObj from Array to Object
strToObj from String to Object

and finally write a function superTypeOf that unlike typeof return a different value for advanced types like Map and Set

Examples

const str = 'hello'
const arr = [ 1, 2, 1, 3 ]
const obj = { x: 45, y: 75, radius: 24 }
const set = new Set()
const map = new Map()
set.add(1)
set.add(2)
set.add(1)
set.add(3)
map.set('a', 1)
map.set('b', 2)
map.set(3, 'c')
map.set(4, 'd')

arrToSet(arr) // -> Set { 1, 2, 3 }
arrToStr(arr) // -> '1213'
setToArr(set) // -> [1, 2, 3]
setToStr(set) // -> '123'
strToArr(str) // -> ['h', 'e', 'l', 'l', 'o']
strToSet(str) // -> Set { 'h', 'e', 'l', 'o' }
mapToObj(map) // -> { a: 1, b: 2, '3': 'c', '4': 'd' }
objToArr(obj) // -> [45, 75, 24]
objToMap(obj) // -> Map { 'x' => 45, 'y' => 75, 'radius' => 24 }
arrToObj(arr) // -> { '0': 1, '1': 2, '2': 1, '3': 3 }
strToObj(str) // -> { '0': 'h', '1': 'e', '2': 'l', '3': 'l', '4': 'o' }

superTypeOf(map) //         -> 'Map'
superTypeOf(set) //         -> 'Set'
superTypeOf(obj) //         -> 'Object'
superTypeOf(str) //         -> 'String'
superTypeOf(666) //         -> 'Number'
superTypeOf(NaN) //         -> 'Number'
superTypeOf(arr) //         -> 'Array'
superTypeOf(null) //        -> 'null'
superTypeOf(undefined) //   -> 'undefined'
superTypeOf(superTypeOf) // -> 'Function'
