Simplest way to create an array from an associative array which
its contains keys and values?
For example if i have an associative array like this:
["one":"1", "two":"2"]
What's the easiest way to create a dynamic array that looks
like this:
["one", "1", "two", "2"]
I know it can be done via a loop, but is there a more idiomatic
way to achieve this?
As someone with little experience with functional programming, I
am just curious - having browsed through the thread - if the
various solutions proposed here would really be considered more
'idiomatic' D. Or if they were posted because the OP asked about
avoiding the foreach() loop.
In other words while:
auto range = aa.byKey.map!(a => chain(a.only, aa[a].only));
string[] array = range.join;
Saves a few lines of code, and looks cooler, it seems that the
trivial foreach loop version is very easy:
string[] array;
foreach (key, value; aa) {
array ~= key;
array ~= value;
}
