';' expected.ts(1005) error is shown in a .js file #import statement. Using "TypeScript and JavaScript Language Features"

• VS Code Version: 1.78.2
• OS Version: Windows 10 Pro x64 22H2

Steps to Reproduce:

1. Enable the "TypeScript and JavaScript Language Features" extension included in VSCode.
2. Create a new .js file.
3. Add #include "SomeScript.js"; to the top of the file.
4. Observe that the extension is marking the line as a problem with the cause of ';' expected.ts(1005)

The #include statement above is perfectly valid JavaScript from what I understand. Why is it throwing a TypeScript error in a JavaScript file?

Not any javascript I'm familiar with. You want import instead: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import
