splice()とslice()の違い

・spliceメソッドを使うと元になった配列要素が変更されてしまう
 sliceメソッドは元の配列を変更しない
・slice()は文字列型のメソッド

arr.slice([start[, end]])
splice(start, deleteCount)

配列の最後から一定数文字を取得して、
配列をつなげて、特定の文字が含まれてるかどうか調べる

arr.splice(-secretCode.length -1  , pressed.length - secretCode.length);
if(arr.join('').includes(secretCode)){
}
