False typescript errors in the browser window

Question

I have a line of code written using Typescript. The label argument has a string type this is clearly visible in the screenshot

At the same time, after compiling the code, an error appears in the browser window that says that label has the type any.

Please tell me what is the cause and how can I fix this behavior

If you are sure that the label param will be always a string, specify the type. (label: string) — igmani

The type in the popup looks like some built-in tool in your IDE (VSC probably?) however the error in the browser comes from the typescript compiler. Maybe there is a difference in versions between both of these tools, because it's strange that the "string" value is not infered. — kind user

Specify the label to be of type string

mdValue = filterData.value.map((label: string) => {
 // ...
});

indeed, the error has disappeared. But such inconsistent behavior of the compiler in the browser and ICE remains a mystery to me. Do you have any ideas how to fix it or what kind of material to study on this issue?
