| 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. |
