The legacy generator function expression is a SpiderMonkey-specific feature, and will be removed at some point. For future-facing usages, consider using the
function* expression
.The function
keyword can be used to define a legacy generator function inside an expression. To make the function a legacy generator, the function body should contain at least one yield
expression.
