Challenge: Create a Sum Function

Task

Implement a function sum that takes three arguments (a, b, and c) and returns their sum.

Next, call this function twice, using the following sets of arguments:

Use 24, 12, and 32 for the first function call and store the result in the variable sum1.
Use 12, 42, and 5 for the second function call and store the result in the variable sum2.

Finally, print the results of both function calls.


              123456789
            
function sum(___, ___, ___) {
  ___ a + b + c;
};

let sum1 = ___(___, ___, ___);
let sum2 = ___(___, ___, ___);

console.log("sum1 =", ___);
console.log("sum2 =", ___);

The output should be:


python

Use the return keyword inside the function body.
Use the function name to call this function.
Choose values yourself.


              123456789
            
function sum(a, b, c) {
  return a + b + c;
}

let sum1 = sum(24, 12, 32);
let sum2 = sum(12, 42, 5);

console.log("sum1 =", sum1);
console.log("sum2 =", sum2);

¿Todo estuvo claro?
