Recursive Filter and Manipulation on Complex Objects
Sun May 05 2024 Recursive Employee Search:
Implemented a function getAllSoftwareEngineerRoles that traverses the company's hierarchical department structure to find and list all employees with the role "Software Engineer."
Mapping and Filtering:
For each department and its subdepartments, the function uses map and filter to extract employee names based on their role, recursively including results from deeper levels.
Data Aggregation:
Combines all results using flat() to produce a flat array of employee names, showcasing effective data traversal and manipulation across complex nested structures
Recursive Salary Assignment:
Developed addEmployeeSalary to traverse the entire departmental structure, adding a randomized salary to each employee.
Iterative and Recursive Processing:
For each department, iterates through its employees to assign salaries and recursively processes any subdepartments.
