IterationStatement : while ( Expression ) Statement

1. Let V = undefined.

2. Repeat

a. Let exprRef be the result of evaluating Expression.

b. Let exprValue be GetValue(exprRef).

c. ReturnIfAbrupt(exprValue).

|
d. If ToBoolean(exprValue) is false, return NormalCompletion(V).

e. Let stmt be the result of evaluating Statement.

f. If LoopContinues (stmt, labelSet) is false, return

Completion(UpdateEmpty(stmt, V)).
