For reference: example here
I am trying to access a struct field using a variable key, to explain in PHP you can do the below.
$arr = ["test" => "foo"];
$key = "test";
$result = $arr[$key];
Or in Javascript you can do the below
const obj = {"test": "foo"}
const key = "test"
const result = obj[key]
Is this possible with go structs? I have searched for this functionality, but the answers always seem to point to the reflect package and running a for loop over the struct fields.
My code (linked above) gets the compile error of invalid operation: p[key] (type Post does not support indexing)
which makes sense, but I can't find a way around this.
