Function std.array.join
Eagerly concatenates all of the ranges in ror
together (with the GC)
into one array using sep
as the separator if present.
ElementEncodingType!(ElementType!RoR)[] join(RoR, R)
(
RoR ror,
scope R sep
)
if (isInputRange!RoR && isInputRange!(Unqual!(ElementType!RoR)) && isInputRange!R && is(Unqual!(ElementType!(ElementType!RoR)) == Unqual!(ElementType!R)));
ElementEncodingType!(ElementType!RoR)[] join(RoR, E)
(
RoR ror,
scope E sep
)
if (isInputRange!RoR && isInputRange!(Unqual!(ElementType!RoR)) && is(E : ElementType!(ElementType!RoR)));
ElementEncodingType!(ElementType!RoR)[] join(RoR)
(
RoR ror
)
if (isInputRange!RoR && isInputRange!(Unqual!(ElementType!RoR)));

Example
writeln(join(["hello", "silly", "world"], " ")); // "hello silly world"
writeln(join(["hello", "silly", "world"])); // "hellosillyworld"
writeln(join([[1, 2, 3], [4, 5]], [72, 73])); // [1, 2, 3, 72, 73, 4, 5]
writeln(join([[1, 2, 3], [4, 5]])); // [1, 2, 3, 4, 5]
const string[] arr = ["apple", "banana"];
writeln(arr .join(",")); // "apple,banana"
writeln(arr .join()); // "applebanana"
