Codecademy - More array methods

const groceryList = ['orange juice', 'bananas', 'coffee beans', 'brown rice', 'pasta', 'coconut oil', 'plantains'];

// remove the first item using shift
groceryList.shift()
console.log(groceryList);

// add 'popcorn' to the front of the array using unshift
groceryList.unshift('popcorn');
console.log(groceryList);

// extract a part of the array based on start and end position (non-inclusive)
console.log(groceryList.slice(1,4));

// shows that the list is non-mutated after performing a slice operation
console.log(groceryList);

// find the index of a particular element using indexOf
const pastaIndex = groceryList.indexOf('pasta');
console.log(pastaIndex);
