Quirky JS

var a = {
  i: 1,
//   toString: function () {
//     return a.i++;
//   }
  valueOf: function () {
    return a.i++;
  }
  // When using loose equality, due to type coersion, if one of the operands is of a different type than the other, the engine will attempt to convert one to the other. In the case of an object on the left and a number on the right, it will attempt to convert the object to a number by first calling valueOf if it is callable, and failing that, it will call toString
  // every time one of these is called, i is being incemented. The == operator calls valueOf then toString
}

if ( a==1 && a==2 && a==3 ) {
  console.log("Hello Quirky 1!");
