 We’ve renamed JS errors to `JsError.t` to better distinguish them from the `Result.Error` variant. Since JavaScript allows throwing anything (not only proper Error objects), the previous way of catching JS exceptions was unsafe:
 
-```res
+```rescript
 let foo = switch myUnsafeJsResult() {
 | exception Exn.Error(e) => Error(e->Error.message)
-  // ☝️ this will crash if `e` is undefined or null
+// ☝️ this will crash if `e` is undefined or null

 The new recommended pattern is:
 
-```res
+```rescript
 let foo = switch myUnsafeJsResult() {
-| exception JsExn(e) => Error(e->JsExn.message))

 Utility helpers for working with JS errors are now in `JsError`, eg:
 
-```res
+```rescript
 JsError.throw(JsError.RangeError.make("the payload should be below 16"))
 ```
