This API can be used to calculate the New Salary of an employee. The calculation logic is as below:
New Salary = Current Salary + (Performance Rating * Salary Multiplier).
Salary Multiplier is:
2000 for engineer
3000 for manager
4000 for director
So, if the Current Salary of a Manager is 80000 and she has a performance rating of 4.5, then her New Salary will be:
80000 + (4.5 * 3000) = 93500
It contains the following Route:
- /newSalary
