[筆記]比較UTC時間

new Date是非常好用的語法，不管是給UTC時間、還是地區時間，都可以幫你無痛轉成UTC的時間。
比較也是很簡單！直接做比較運算子就好！

let nowDate: Date = new Date();  
let endDate: Date = new Date( "2021-10-15T12:00:00+00:00");
let myDate: Date = new Date( "2021-10-15T16:22:00");
console.log(nowDate);
console.log(endDate);
console.log(myDate);
if (nowDate > endDate){
    console.log("Bigger");
}else{
    console.log("Smaller");
}
if (nowDate > myDate){
    console.log("Bigger");
}else{
    console.log("Smaller");
}

結果：

[LOG]: nowDate: "2021-10-15T08:22:47.110Z" [LOG]: endDate: "2021-10-15T12:00:00.000Z" [LOG]: myDate: "2021-10-15T08:22:00.000Z" [LOG]: nowDate vs endDate => "Smaller" [LOG]: nowDate vs myDate => "Bigger"
