// for loop shorthand javascript

// Longhand:

const animals = ['Lion', 'Tiger', 'Giraffe'];

for (let i = 0; i < animals.length; i++){

  console.log(animals[i]); 

// output: 

// Lion

// Tiger

// Giraffe

}

​

// Shorthand:

for (let animal of animals){

    console.log(animal);

// Lion

// Tiger

// Giraffe

}

​

// If you just wanted to access the index, do:

for (let index in animals){

  console.log(index);

// 0

// 1

// 2

}

​

// This also works if you want to access keys in a literal object:

const obj = {continent: 'Africa', country: 'Kenya', city: 'Nairobi'}

for (let key in obj)

  console.log(key) 

// continent

// country 

// city

// Shorthand for Array.forEach:

function logArrayElements(element, index, array) {

  console.log(index + " = " + element);

}

["first", "second", "third"].forEach(logArrayElements);

// 0 = first

// 1 = second

// 2 = third
