const fruits = ['mango', 'papaya', 'pineapple', 'apple'];

// Iterate over fruits below

// Normal way
fruits.forEach(function(fruit){
  console.log('I want to eat a ' + fruit)
});

forEach

const arraySparse = [1,3,,7]
let numCallbackRuns = 0

arraySparse.forEach((element) => {
  console.log(element)
  numCallbackRuns++
})

console.log("numCallbackRuns: ", numCallbackRuns)

// 1
// 3
// 7
// numCallbackRuns: 3
// comment: as you can see the missing value between 3 and 7 didn't invoke callback function.
