JavaScript勉強の記録その23:例外処理

Last updated at Posted at 2020-02-02

#JavaScriptの例外処理
PHPに似てるなと思いましたが、tryとcatchで例外処理ができます。
JavaScriptではあまり使わないかもですが。

index.js
const name = "okuno"
try {
  console.log(name.makeUpperCase());
} catch (e) {
  console.log('さーせん、エラーでたのでやり直してください');
}
//=>さーせん、エラーでたのでやり直してください
