数日に一個は、アプリ制作をしたいと思って、qiita徘徊中
でみつけた

外部APIを利用して、データベースとし、チャットアプリ

しかし、コードをみてもわからない。

functionの前にある : ってなに?

しかし、解決した。

<script>
  let Member = function(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;
  };
  Member.prototype = {
    getName : function() {
      return this.lastName + '' + this.firstName;
    },
    toString : function() {
      return this.lastName + this.firstName;
    }
  };
  let mem = new Member('sudo', 'eishun');
  console.log(mem.getName());
  console.log(mem.toString());
</script>

オブジェクトのメンバーにとなる関数 を . を使わず : で
表現しているだけなのね。
