We are required to write a JavaScript function that takes in an array with both positive and negative numbers and returns the absolute sum of all the elements of the array. We are required to do this without taking help of any inbuilt library function.
For example: If the array is −
const arr = [1, -5, -34, -5, 2, 5, 6];
Then the output should be −
58
Therefore, let’s write the code for this function −
The code for this will be −
const arr = [1, -5, -34, -5, 2, 5, 6]; const absoluteSum = arr => { let res = 0; for(let i = 0; i < arr.length; i++){ if(arr[i] < 0){ res += (arr[i] * -1); continue; }; res += arr[i]; }; return res; }; console.log(absoluteSum(arr));
The output in the console will be −
58
