1つのjsファイルで効果音を鳴らす

音データをdata uriとしてjsファイル内に保持します。また、高速でタイプ音を漏れなくならせるように、8個のaudioオブジェクトを用意して、順番に呼び出しながら音を鳴らします。

ソースコード例です。

sound.js

const sound = {
    audio:[],
    index:0,
    init:()=>{
        for(let i=0;i<8;i++){
            sound.audio.push(new Audio(sound.data_uri));
        }
    },
    play:()=>{
        sound.audio[sound.index%sound.audio.length].play();
        sound.index += 1;
    },
