// What others do (simplified)
class DynamoDBTool {
  constructor() {
    this.client = new DynamoDBClient({ profile: globalProfile });
  }
  
  switchProfile(newProfile) {
    // Rebuilds everything 😱
    this.client = new DynamoDBClient({ profile: newProfile });
    this.clearAllQueries();
    this.resetUI();
  }
}

// What we do
class DynomateTab {
  constructor(profile, region) {
    // Each tab gets its own client
    this.client = new DynamoDBClient({ profile, region });
    this.sessionManager = new SessionManager(profile);
    this.queryHistory = new QueryHistory();
  }
  // No global state to worry about
}
