How to switch to v8.2.0

1

Hi, everyone.
My bsb version is v8.4.2, which is the latest, now.
However, the only example from the official site that compiled successfully on my machine is <v8.2.0(ML, the older one).

external random: unit -> float = "random"
[@@bs.val][@@bs.scope "Math"]

let someNumber = random ()

What I expected is an example of v8.2.0 compiled successfully.

How to switch to 8.2.0? I’ve tried to look over the configuration section, but I didn’t found it. (Aren’t the version of bsb & version of language synchronized?)

What’s your file extension? If you’re using .res, you should use the new (ReScript) syntax, like this:

@bs.val @bs.scope("Math")
external random: unit => float = "random"

let someNumber = random()

@bs.val @bs.scope(("window", "location", "ancestorOrigins"))
external length: int = "length"

OTOH, if you use the old syntax, the extension should be .re (ReasonML).
