2020年に開講したフランス発のエンジニア養成機関42 Tokyo(フォーティーツートーキョー)の在校生によるAdvent Calendarです。
在校生、元在校生、スタッフなど、42Tokyoと関わりがある方であれば投稿が可能です。

あまり情報の明かされていない42 Tokyo内部に関する話や，42 Tokyoの学生が日々学んできたこと、42での技術を活かした個人の制作、association活動やPiscine受験記、42から離れた後、振り返ってみてどうだったかなど、42Tokyoに関することであればどんな内容でも構いません。（あまりにもエンジニアリング、プログラミングに関係ないような内容であればnoteなど外部ブログで書いた記事を貼るのを推奨します。多分そっちのほうが伸びやすいので。）

2024年度アドベントカレンダーはこちら

注意事項
＊42の在校生が個人で作成したアドベントカレンダーです。　42Tokyoの公式が運営しているカレンダーではないため、ご注意ください。
＊Piscineの詳細な内容、課題の詳細や答えなど、42Tokyo公式が公開を禁止している内容については絶対に載せないでください。
