  25     Description:
  26
  27     The grammar for a ConditionalExpression in ECMAScript is a little bit
  28     different from that in C and Java, which each allow the second
  29     subexpression to be an Expression but restrict the third expression to
  30     be a ConditionalExpression.  The motivation for this difference in
  31     ECMAScript is to allow an assignment expression to be governed by either
  32     arm of a conditional and to eliminate the confusing and fairly useless
  33     case of a comma expression as the center expression.
