Error in Typescript tuple linting is inconsistent in vscode

While following a tutorial video on utilizing types in TypeScript, I encountered an inconsistency between my text editor's linting and the content of the video.

The video displays this:

https://i.sstatic.net/awm9f.png

However, mine shows like this:

https://i.sstatic.net/3sTbZ.png

https://i.sstatic.net/yelmt.png

Even after making changes to the code to eliminate errors according to linting rules, the errors persist:

I am left wondering about this inconsistency. It should be noted that I am using TypeScript 3.3.x while the video refers to version 3.1.x.

Answer №1

The video announced the array in the following manner:
