    * Split no-unused-vars ESLint config to multiple lines
    
    * Exempt variables prefixed with underscore from no-unused-vars rule
    
    This is useful when e.g. using object spread operator to remove only a
    certain field from the object.
    
    For example, this can be used to ignore a property from React
    component's `this.props`:
    
        render() {
            const { someAttribute: _unused, ...rest } = this.props;
            return <pre>{ JSON.stringify(rest) }</pre>;
        }
