Legacy generator function expression

Our volunteers haven't translated this article into Tiếng Việt yet. Join us and help get the job done!

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.

Syntax

function [name]([param1[, param2[, ..., paramN]]]) {
   statements
}

Parameters

name
The function name. Can be omitted, in which case the function is anonymous. The name is only local to the function body.
paramN
The name of an argument to be passed to the function. A function can have up to 255 arguments.
statements
The statements which comprise the body of the function. This should contain at least one yield expression.

Description

An overview of the usage is available on the Iterators and Generators page.
