const arrAvg = arr => arr.reduce((a,b) => a + b, 0) / arr.lengthconst scores = [ 20, 50, 75, 100, 115 ];
let total = 0;
for ( let i = 0; i < scores.length; i++ ) {
total += scores[i];
}
console.log( total / scores.length );
const 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]));
