When returning an object from an arrow function, it seems that it is necessary to use an extra set of {}
and a return
keyword because of an ambiguity in the grammar.
That means I can’t write p => {foo: "bar"}
, but have to write p => { return {foo: "bar"}; }
.
If the arrow function returns anything other than an object, the {}
and return
are unnecessary, e.g.: p => "foo"
.
p => {foo: "bar"}
returns undefined
.
A modified p => {"foo": "bar"}
throws “SyntaxError
: unexpected token: ':
'”.
Is there something obvious I am missing?
