find the average of all elements in an array in javascript

index.tsx
// define an array
const myArray = [1, 2, 3, 4, 5];

// initialize a variable to store the sum
let sum = 0;

// use a loop to iterate through each element in the array and calculate the sum
for(let i = 0; i < myArray.length; i++){
  sum += myArray[i];
}

// calculate the average by dividing the sum by the number of elements in the array
const avg = sum / myArray.length;

console.log(`The average of all elements in the array is ${avg}`);
