/**
File Name: expression-001.js
Corresponds to: ecma/Expressions/11.12-2-n.js
ECMA Section: 11.12
Description:
The grammar for a ConditionalExpression in ECMAScript is a little bit
different from that in C and Java, which each allow the second
subexpression to be an Expression but restrict the third expression to
be a ConditionalExpression. The motivation for this difference in
ECMAScript is to allow an assignment expression to be governed by either
arm of a conditional and to eliminate the confusing and fairly useless
case of a comma expression as the center expression.
