JavaScriptにおける名前付き引数

const login = (email, password, username) => {
  console.log("email:", email);
  console.log("password:", password);
  console.log("username:", username);
};

const email = "hoge@test.com"
const password = "fuga"
const username = "hoge"

// 引数を渡す順番を間違えているので、意図した処理ができない
login(username, email, password);

def login(email:, password:, username:)
  puts "email: #{email}"
  puts "password: #{password}"
  puts "username: #{username}"
end

email = "hoge@test.com"
password = "fuga"
username = "hoge"

login(username: username, email: email, password: password)

const login = ({ email, password, username }) => {
  console.log("email:", email);
  console.log("password:", password);
  console.log("username:", username);
};

const email = "hoge@test.com";
const password = "fuga";
const username = "hoge";

// どちらも正しく動作する
login({ email, password, username });
login({ username, password, email });
