//Q-1. Create an Array of Salaries, Now do the Sum of Salaries who is greater than 10000.
//Hint : reduce function

var salary = [10000, 5000, 25000, 30000, 9000, 13000, 7500];

var sumSalary = salary.reduce((accumulator, currentValue) => accumulator + (currentValue > 10000 ? currentValue : 0), 0);
console.log("The sum of salary greater than 10,000 : ", sumSalary);


//Q-2. Get the Max Salary from the Array
//Hint : reduce function

var maxSalary = salary.reduce((accumulator, currentValue) => (accumulator > currentValue ? accumulator : currentValue));
console.log("The maximum salary : ", maxSalary);


//Q-3. Count Those Salaries whose > 10000, note : don't use filter.
//Hint : reduce function

var countSalary = salary.reduce((accumulator, currentValue) => accumulator + (currentValue > 10000 ? 1 : 0), 0);
console.log("Number of salaries greater than 10,000 : " + countSalary);


//Q-4. Maintain an Array of Employees. (Array of Objects), Now Sort the Employee by Name and Salary.

//sort by salary
employees.sort((a, b) => a.salary-b.salary);

//sort by name
employees.sort((a, b) =>

    const nameB = b.name.toUpperCase();

//Q-5. In Employee Salaries add 10% Tax in Each Employee Salary and Store in a new Array, So don't modify the Orginal Array.
