JavaScriptでシンプルなオブジェクトを作成する

Last updated at Posted at 2022-05-14

オブジェクトはプロパティやメソッドから構成されている。

プロパティとは、オブジェクトの状態や特性を表すための情報のことであり、メソッドはオブジェクトを操作するためのものである。

sample.js
'use strict';
let sampleObject = {
  numarr:[1,2,3],
  name: 'Hanako',
  greet:function(){
    console.log(`Hello,${this.name}`);
  }
}

console.log(sampleObject.numarr);
sampleObject.greet();

結果:[ 1, 2, 3 ]
Hello,Hanako
