Visual Studio Code: [ts] 'ListrikPage' is declared but its value is never read

In visual studio code sometimes there are codes that are being highlighted dimly. I wonder what’s wrong?

Also there is this message next to it:

[ts] 'ListrikPage' is declared but its value is never read.

module "d:/Marketing Tools/IDS/solusipay2/src/pages/listrik/listrik"

Thanks in advance.

probably

Exactly what it says: you declare something, then never use it’s value in the code.
