The members’ note now comes out right, so the next part of Ruth’s script to port is the course picker. On a racing morning, the wind direction picks one of three courses. Ruth decides with a second match, where some cases cover several directions and a last case catches the rest.
A JavaScript case holds one value, so you need another way to say “either of these.” You’ll share one body between cases, give the leftover directions a fallback, and see when JavaScript developers look the answer up instead.
Stack Cases That Share a Course
Ruth’s match lists every direction that gets the same course in one case, joined with |:
direction = "NE"
match direction:
case "N" | "NE":
course = "harbour triangle"
case "S" | "SW" | "W":
course = "outer trapezoid"
case _:
course = "short windward-leeward"
print(course)
On the main morning, the wind is from the northeast, so the script prints harbour triangle.
A JavaScript case doesn’t close off a block. It marks where execution starts, and execution runs on until a break. Fall-through broke the members’ note, but here it does the work you want. A case with no body falls into the next one, so directions that share a course become stacked cases, one label per line, above one body and one break:
