HTTP Headers for the JavaScript target: https://developer.mozilla.org/en-US/docs/Web/API/Headers

Example: cmd: -r:off

import std/jsheaders

block:
  let header: Headers = newHeaders()
  header.add("key", "value")
  assert header.hasKey("key")
  assert header.keys() == @["key".cstring]
  assert header.values() == @["value".cstring]
  assert header["key"] == "value".cstring
  header["other"] = "another".cstring
  assert header["other"] == "another".cstring
  assert header.entries() == @[("key".cstring, "value".cstring), ("other".cstring, "another".cstring)]
  assert header.toCstring() == """[["key","value"],["other","another"]]""".cstring
  header.delete("other")
  assert header.entries() == @[("key".cstring, "value".cstring)]
  header.clear()
  assert header.entries() == @[]
  assert header.len == 0

block:
  let header: Headers = newHeaders()
  header.add("key", "a")
  header.add("key", "b")  ## Duplicated.
  header.add("key", "c")  ## Duplicated.
  assert header["key"] == "a, b, c".cstring
  header["key"] = "value".cstring
  assert header["key"] == "value".cstring

block:
  let header: Headers = newHeaders()
  header["key"] = "a"
  header["key"] = "b"  ## Overwrites.
  assert header["key"] == "b".cstring
