/**

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.
