double[3] result;
Json json = res.readJson;
for(int i = 0; i < json.length; i++){
result[i] = json[i].to!double;
}
I'd prefer to do something like:
result = res.readJson[].map!(to!double);
Use std.array.array (alias: std.range.array) to make the range
returned my map!(to!double) into an array.
Note that the result of map isn't actually evaluated until it is
iterated. std.array.array will iterate and collect.
https://dlang.org/phobos/std_array.html#array
result = res.readJson[].map!(to!double).array;
should work perfectly.
