The legacy generator function is a SpiderMonkey-specific feature, and will be removed at some point. For future-facing usages, consider using function*.

The legacy generator function statement declares legacy generator functions with the specified parameters.

You can also define functions using the Function constructor with functionBody and at least one yield expression, and a legacy generator function expression.

Syntax

function name([param,[, param,[..., param]]]) {
   [statements]
}
name
The function name.
param
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.
