ESLint v10.3.0 released

Highlights

no-unused-private-class-members Suggestions

The no-unused-private-class-members rule now provides suggestions to remove reported unused private class members.

For example, for the following code, in which the rule reports #doSomethingElse as unused:

class C {

    /**
     * My public method.
     */
    doSomething() {
    }

    /**
     * My private method.
     */
    #doSomethingElse() {
    }

}

It will now suggest removing #doSomethingElse. After applying the suggestion, the method and related comment will be removed:

class C {

    /**
     * My public method.
     */
    doSomething() {
    }

}
