Implement a function which is used to return the sum of elements of an array code example
Example 1: sum of an array
const sum = (...args) => args.reduce((a, b) => a + b, 0);
console.log(sum(1,2,3)); // returns 6
Example 2: Write a function that takes an array of number values and returns the sum.
function amountTotal(amount) {
var total = 0;
for (i = 0; i < amount.length; ++i) {
total += amount[i]; // add each element in an array to total
}
return total;// return sum of elements in array
}
