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 ror, R sep)
ElementEncodingType!(ElementType!RoR)[] join(RoR ror, E sep)
ElementEncodingType!(ElementType!RoR)[] join(RoR ror)
ElementEncodingType!(ElementType!RoR)[]
join
(
RoR
)
(
RoR ror
)
if (
isInputRange!RoR &&
isInputRange!(Unqual!(ElementType!RoR))
)

Parameters

ror RoR: An input range of input ranges

Return Value

Type: ElementEncodingType!(ElementType!RoR)[]

An array of elements

Examples

assert(join(["hello", "silly", "world"], " ") == "hello silly world");
assert(join(["hello", "silly", "world"]) == "hellosillyworld");

assert(join([[1, 2, 3], [4, 5]], [72, 73]) == [1, 2, 3, 72, 73, 4, 5]);
assert(join([[1, 2, 3], [4, 5]]) == [1, 2, 3, 4, 5]);

const string[] arr = ["apple", "banana"];
assert(arr.join(",") == "apple,banana");
assert(arr.join() == "applebanana");
