join() function

주어진 iterable의 모든 요소를 구분자로 구분한 문자열로 반환합니다.

Signature:

declare function join<A extends readonly []>(sep: string, iterable: A): "";

Example

const joined = join('~', ['a', 'b', 'c']); // 'a~b~c'

// with pipe
pipe(
 [1, 2, 3, 4],
 map(a => a + 10),
 filter(a => a % 2 === 0)
 join('-'),
); // '12-14'

await pipe(
 Promise.resolve([1, 2, 3, 4]),
 join('-'),
); // '1-2-3-4'

// with toAsync
await pipe(
 [Promise.resolve(1), Promise.resolve(2), Promise.resolve(3), Promise.resolve(4)],
 toAsync,
 join('-'),
); // '1-2-3-4'
