-The next sorting method we'll look at is insertion sort. This method works by building up a sorted array at the beginning of the list. It begins the sorted array with the first element. Then it inspects the next element and swaps it backwards into the sorted array until it is in sorted position. It continues iterating through the list and swapping new items backwards into the sorted portion until it reaches the end. This algorithm has quadratic time complexity in the average and worst cases.
+Il prossimo metodo di ordinamento che vedremo è Insertion Sort. Questo metodo funziona costruendo un array ordinato all'inizio della lista. Esso inizia l'array ordinato con il primo elemento. Poi ispeziona l'elemento successivo e lo scambia all'indietro nell'array ordinato fino a quando non è in posizione ordinata. Continua a iterare attraverso la lista e a scambiare nuovi elementi all'indietro nella porzione ordinata fino a raggiungere la fine. Questo algoritmo ha una complessità di tempo quadratica nei casi medi e peggiori.

-Here we will move on to an intermediate sorting algorithm: quick sort. Quick sort is an efficient, recursive divide-and-conquer approach to sorting an array. In this method, a pivot value is chosen in the original array. The array is then partitioned into two subarrays of values less than and greater than the pivot value. We then combine the result of recursively calling the quick sort algorithm on both sub-arrays. This continues until the base case of an empty or single-item array is reached, which we return. The unwinding of the recursive calls return us the sorted array.
+Qui passeremo ad un algoritmo di ordinamento intermedio: Quick Sort. Quick Sort è un approccio efficiente e ricorsivo di logica divide-et-impera per l'ordinamento di un array. In questo approccio, viene scelto un valore pivot nell'array originale. L'array viene poi suddiviso in due sottoarray di valori inferiori e superiori al valore pivot. Quindi combiniamo il risultato della chiamata ricorsiva dell'algoritmo Quick Sort su entrambi i sotto-array. Questo continua fino al raggiungimento del caso base di un array vuoto o di un singolo oggetto, al che torniamo indietro. Lo svolgimento delle chiamate ricorsive restitusce l'array ordinato.
 
-Quick sort is a very efficient sorting method, providing *O(nlog(n))* performance on average. It is also relatively easy to implement. These attributes make it a popular and useful sorting method.

-**Instructions:** Write a function `quickSort` which takes an array of integers as input and returns an array of these integers in sorted order from least to greatest.

+**Istruzioni:** Scrivi una funzione `quickSort` che prende un array di interi come input e restituisce un array di questi interi in ordine dal più piccolo al più grande. Anche se la scelta del valore pivot è importante, per i nostri scopi andrà bene qualsiasi pivot. Per semplicità, si potrebbe usare il primo o l'ultimo elemento.

-`indexOf()` pode ser incrivelmente útil para verificar rapidamente a presença de um elemento em um array. Definimos uma função, `quickCheck`, que recebe um array e um elemento como argumentos. Modifique a função usando `indexOf()` para que retorne `true` se o elemento passado existe no array, e`false` caso não exista.

 Na ciência da computação, <dfn>dado</dfn> é qualquer coisa que tenha significado ao computador. JavaScript fornece oito <dfn>tipos de dados</dfn> diferentes que são `undefined`, `null`, `boolean`, `string`, `symbol`, `bigint`, `number` e `object`.
 
-Por exemplo, os computadores distinguem números, como o número`12`, e`strings`, como o `"12"`, `"dog"`, ou`"123 cats"`, as quais são coleções de caracteres. Computadores podem realizar operações matemáticas em um número, mas não em string.

 <dfn>Variáveis</dfn> permitem aos computadores armazenar e manipular dados de forma dinâmica. Eles fazem isso usando um "rótulo" para apontar ao dado ao invés de usar o próprio dado. Qualquer uma dos 8 tipos de dados podem ser armazenados em variável.

-Nós iremos agora usar nosso conhecimento de strings para criar um "[Mad Libs](https://en.wikipedia.org/wiki/Mad_Libs)" estilo de jogo de palavras que chamamos de "Palavras em Branco". Você irá criar uma frase no estilo "Preencha os Espaços em Branco" (opcionalmente humorosa).
+Nós vamos agora usar nosso conhecimento de strings para criar um "[Mad Libs](https://en.wikipedia.org/wiki/Mad_Libs)" estilo de jogo de palavras que chamamos de "Palavras em Branco". Você irá criar uma frase no estilo "Preencha os Espaços em Branco" (opcionalmente humorosa).
 
 Em um jogo "Mad Libs", você recebe frases com algumas palavras faltando, como substantivos, verbos, adjetivos e advérbios. Você então irá preencher os pedaços faltantes com palavras de sua escolha em uma forma que a frase completa faça sentido.
