Client-side Rendering とは
Reactによるクライアント・サイド・レンダリング（CSR）
では、ブラウザは最小限のHTMLページと、そのページに必
要なJavaScriptをダウンロードする。
In Client-Side Rendering (CSR) with React, the browser downloads a
minimal HTML page and the JavaScript needed for the page.

php-wasm とは
Slide 24
Slide 24 text
php-wasm とは
PHPをWebAssembly（Wasm）上で動作させるための技術で
す。これにより、ブラウザ上でPHPコードを実行することが
可能になります。

WebAssembly（Wasm） とは
Slide 26
Slide 26 text
WebAssembly（Wasm） とは
WebAssembly は現代のウェブブラウザーで実行できる新し
い種類のコードです。ネイティブに近いパフォーマンスで動
作する、コンパクトなバイナリー形式の低レベルなアセンブ
リー風言語です。さらに、 C/C++、C# や Rust などの言語
のコンパイル先となり、それらの言語をウェブ上で実行する
ことができます。 WebAssembly は JavaScript と並行して
動作するように設計されているため、両方を連携させること
ができます。
