type Equal<A, B> = (<T>() => T extends A ? 1 : 0) extends <T>() => T extends B
  ? 1
  : 0
  ? true
  : false

class Point {
  x: number
  y: number

  constructor(x: number, y: number) {
    this.x = x
    this.y = y
  }
}
interface PointConstructor {
  new (x: number, y: number): Point
}

type bo = Equal<typeof Point, PointConstructor> // type bo = false
type bo1 = typeof Point extends PointConstructor ? true : false // type bo1 = true
type bo1 = PointConstructor  extends typeof Point ? true : false // type bo2 = true

Why are the Point constructor types and PointConstructor interfaces different In the Equal type tool?
