It's a bit unclear to me how arrow functions react to semicolons, for
example:
var a = (c) => {
var b = 2;
b * c;
}
a(4);
To me, it seems like this should return undefined. After all, the last
statement in the function is empty. To actually return b * c, you should
drop the semicolon:
var a = (c) => {
var b = 2;
b * c
}
a(4);
This would be consistent with, for example, Rust and would help avoid
annoying accidental returns (see [1] for discussion about this wrt
CoffeeScript).
Cheers,
