💻 Code

const myObj = {};
Object.values(myObj);

with "Target:" set to a pre-ES2017 example, like ES5.

🙁 Actual behavior

On hover, the error message says, "Property 'values' does not exist on type 'ObjectConstructor'. Do you need to change your target library? Try changing the lib compiler option to 'es2017' or later.(2550)"

The capitalization in this error message does not match the auto-generated capital "ES2017" suggestion in VSCode when filling out the lib compiler option.

🙂 Expected behavior

For consistency, I think the error message should say, "Property 'values' does not exist on type 'ObjectConstructor'. Do you need to change your target library? Try changing the lib compiler option to 'ES2017' or later.(2550)", instead.

Here, the capital "ES2017" matches the suggested "ES2017" that appears when typing in a tsconfig.json file in VSCode.

まず TypeScript コンパイラの診断から報告された Object.values エラーを検索し、ES5 を対象とするリンク先の Playground コードで再現します。診断が VSCode の補完に表示されるものと同じ ES2017 の大文字・小文字表記を使用していることを確認し、その後、サンプルと ES2017 より前のターゲットに対して更新後の文言を検証します。
