Creating and extending custom rules in eslint.

In my code i wrote on VS Code(Containing eslint) most of the cases where a line containing a string. like the below one.

var temp = "Stackoverflow";
var other=temp+" javascript";

I need an auto-fix option in es-lint such that it adds a (a static) comment at the end of line for the lines containing string on VS Code. like this

var temp = "Stackoverflow";//Custom comment
var other=temp+" javascript";//Custom comment

Is there any way of achieving this on eslint using node or VSCode?

Technically, yes, you can create a custom rule with a fixer. The rule would check that every string literal appears on a line that ends in a comment, and add the comment if necessary.

If you can share more information on the purpose of the custom comment, we may be able to provide better guidance.

As mentioned, technically it’s possible, but that would be improper use of the tool. ESLint isn’t meant for things like that. You might want to look into jscodeshift and similar tools.
