Question 15
A developer wrote the following code to test a sum3 function that takes in an array of numbers and returns the sum of the first three numbers in the array. The test passes:
01 let res = sum3([1, 2, 3]);
02 console.assert(res === 6);
03
04 res = sum3([1, 2, 3, 4]);
05 console.assert(res === 6);
A different developer made changes to the behavior of sum3 to instead sum all of the numbers present in the array.
Which two results occur when running the test on the updated sum3 function?
01 let res = sum3([1, 2, 3]);
02 console.assert(res === 6);
03
04 res = sum3([1, 2, 3, 4]);
05 console.assert(res === 6);
