230,688 PointsWhat you see in the syntax portion of the documentation are not code examples. Square brackets in that area are used to indicate that what the terms inside describe is optional.
In this case, they are telling you that the first argument to "setTimeout" will be a function, and there may be other arguments. If so, the next will be a delay, then maybe a value, and so on.
