Tests:

lodash sumBy test

const [value1, value2, value3, value4] = [1, 2, 3, 4]; 
const arr = ['value1', 'value2', 'value3', 'value4'];

const totalSum = _.sumBy(arr, (field) => {
  return arr[field] || 0;
});

const [value1, value2, value3, value4] = [1, 2, 3, 4]; const arr = ['value1', 'value2', 'value3', 'value4'];​const totalSum = _.sumBy(arr, (field) => {  return arr[field] || 0;});

Normal sum test case

const [value1, value2, value3, value4] = [1, 2, 3, 4]; 

const totalSum = (value1 || 0) + (value2 || 0) + (value3 || 0) + (value4 || 0);

 
const [value1, value2, value3, value4] = [1, 2, 3, 4]; ​const totalSum = (value1 || 0) + (value2 || 0) + (value3 || 0) + (value4 || 0);
