"ignoreAccessorPattern" doesn't behave like the TSLint version

My new ESLint config:

        "functional/immutable-data": ["error", {
            ignorePattern: ["^mutable"],
            ignoreAccessorPattern: ["**.mutable*.*", "**.current.*"],
        }],

My old TSLint config:

"no-object-mutation":
  [true, {"ignore-prefix": "mutable", "ignore-pattern": ["**.mutable*", "**.current"]}]

And here the sample code, where it behaves differently:

export class SomeClass {

    private mutableSomething?: string;

    mutate(): void {
        this.mutableSomething = "xx"; // Ignored in TSLint, now reported
    }
}

//

const somethingLikeReactUseRef = { current: "x" };

somethingLikeReactUseRef.current = "y"; // Ignored in TSLint, now reported

Am I doing something wrong?

Yes,

This config should work for your original code (once the update is merged in):

"functional/immutable-data": ["error", {
  "ignoreAccessorPattern": ["**.mutable*", "**.current"],
}]

As only string are being modified in your code, property mutation doesn’t need to be checked. However, to allow for reassigning and property mutation use:

"functional/immutable-data": ["error", {
  "ignoreAccessorPattern": ["**.mutable*.**", "**.current.**"],
}]
