const arrAvg = arr => arr.reduce((a,b) => a + b, 0) / arr.lengthconst avg = arr => {
const sum = arr.reduce((acc, cur) => acc + cur);
const average = sum/arr.length;
return average;
}
console.log(avg([1, 2, 3, 7, 8]));var sum = array.reduce((a, b) => a + b, 0); //get sum of all elements in array
var avg = (sum / array.length) || 0; //get average of all elements in array ;)const sum = times.reduce((a, b) => a + b, 0);
const avg = (sum / times.length) || 0;
console.log(`The sum is: ${sum}. The average is: ${avg}.`);
