Destructuring assignment - JavaScript | MDN

The destructuring assignment syntax is a JavaScript expression that makes it possible to unpack values from arrays, or properties from objects, into distinct variables. const [a, b] = array; const [a, , b] = array; const [a = aDefault, b] = array; const [a, b, ...rest] = array; const [a, , b, ...rest] = array; const [a, b, ...{ pop, push }] = array; const [a, b, ...[c, d]] = array; const { a, b }

配列やオブジェクト形式で代入するヤツ

jsで`[a, b] = [1, 2]`みたいにデータを取り出しつつ新たに変数を定義する構文を"Destructuring assignment"と言うのか。困った時の検索キーワードとして覚えておこう。

“{a, b} = {a:1, b:2}”
