JSの特殊な記述方法 書き殴り

if文

let number = 10
let result = "";

if(number < 10) result = "10未満";
else if (number < 100) result = "100未満";

//一般的な記述
if(number < 10){
 result = "10未満"
}else if (number < 100){
 result = "100未満"
}

分割代入

const user = {
 id:1,
 name:"dossy"
}

let {id,name} = user

console.log(id)
//=>1
