💻 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.

Start by searching the TypeScript compiler diagnostics for the reported Object.values error and reproduce it with the linked Playground code targeting ES5. Confirm that the diagnostic uses the same ES2017 capitalization shown by VSCode completion, then verify the updated wording against the sample and a pre-ES2017 target.
