[Victor Godinho]

Information:

• ESLint version: 8.29.0
• eslint-plugin-regexp version: 1.11.0

Description
The following case reports that RegExp#exec() should be changed

    protected readonly PATH_REGEXP: RegExp = /^.*\//g;

    protected getLogPath(filepath: string): string | undefined {
        const match = filepath.match(this.PATH_REGEXP); // Eslint error: `Use the `RegExp#exec()` method instead`

        return match?.[0];
    }
