JAVASCRIPT: 57.3 Practice - Salary Rise

Question

In JavaScript Course, under ECMAScript 6 > 57.3 Practice.

You need to write a program (using ES6 function/syntax) to calculate the total increase for each employee's salary in an array.

using the percent as an input.

Here's the given array:

var salaries = [3000, 7000, 5000, 15000];

Let's say the input is 10 (percent), the 10 percent of each array is as follows:

300, 700, 500, 1500

Which in total, 3000.

The program needs to output the TOTAL ONLY, I'm having a hard time to figure out how I can display the total only. I was able to display the percent increase for each employee.

Please see my code below:

function main() {
var percent = parseInt(readLine(),10);

console.log(salaryIncrease(percent));
}
var salaries = [3000, 7000, 5000, 15000];
const salaryIncrease = percent => {
//your code goes here
salaries.forEach(v => {
v = (v * percent) / 100;
console.log(v);
});
}

Sample Input: 5

My Output:
150
350
250
750
undefined

Expected Output: 1500

I know I'm not supposed to print each values, but I'm having a hard time on how I can display the sum/total of each value that I printed.

Answer 1

Addition Assignment Operator in Java Script is the answer you are looking for. This is simply a += operation on v. You will want to change v = (v * percent) / 100; to v += (v * percent) / 100;

Answer 2

Hi Jibraeel,

Followed your advice but created a variable first for the total and it works!!

Thank you!

Here's the final code:

function main() {
var percent = parseInt(readLine(),10);

console.log(salaryIncrease(percent));
}
var salaries = [3000, 7000, 5000, 15000];
const salaryIncrease = percent => {
//your code goes here
let total = 0;
salaries.forEach(v => {
total += (v * percent) / 100;
}); return total;
}
