v0.20.0

• DEPRECATE xjs.Object.switch and use native Map
  instead of:

  xjs.Object.switch<number>('A', {
    'A': () => 65,
    'B': () => 66,
    'C': () => 67,
  })() // returns 65
  

  use:

  new Map<string, () => number>([
    ['A', () => 65],
    ['B', () => 66],
    ['C', () => 67],
  ]).get('A')() // returns 65
  

• {Array,Set}.is now check for SameValueZero-ness before checking the given predicate, if any. That means you don’t have to manually check yourself in the predicate if you provide one.

  xjs.Array.is([65, 66, 67], ['65', '66', '67'], (a, b) => a == b)
  

  will test a === b || Object.is(a, b) (the SameValueZero algorithm) first, before checking a == b as given in the predicate.
• upgrade to TypeScript v3.7.x
