Hello,
In SpiderMonkey (and perhaps other JS engines?), there are
conditional catch clauses:
catch (exception if condition)
Could such a feature added to ECMAScript?
Rationale: Although try/catch mechanism was initially intended for
treating errors, it could be used in normal control flow with
non-error condition.
Why not just use normal control flow when you want to express
non-error conditions?
Because you have to remember to re-throw in the "default" case (which is
easy to forget).
