森田賢二さんのJavascript練習問題集を解いてみた Act.1

Posted at

この記事はエンジニア芸人の森田賢二さんが作成したJavascript練習問題集を解く過程における気付きや学びを記録したものである。

問1
Object.assignについて問うた問題。

Object.assign(target, ...sources)

// 別解
const c = {...a, ...b}
// このようにスプレッド構文を使うことによっても、マージ可能。どちらもshallow copyである。

To Do

・ 戻り値はtargetオブジェクトってどういうことかを理解する
・ prototypeとは何かを理解する

ではまた〜
