-Binary search is an **O(log(n))** efficiency algorithm for searching a sorted array to find an element. It operates using the following steps:
+二分搜索是一種 **O(log(n))** 效率的算法，用於在已排序的數組以查找元素。 它通過以下步驟運行：
 
-1. Find the middle `value` of a sorted array. If `value == target` return (found it!).
-1. If middle `value < target`, search right half of array in next compare.
-1. If middle `value > target`, search left half of array in next compare.
+1. 查找已排序數組的中間值 `value`。 如果 `value == target`，則返回（找到了！）。
+1. 如果中間值 `value < target`，則在下一次比較中搜索數組的右半部分。
+1. 如果中間值 `value > target`，則在下一次比較中搜索數組的左半部分。
 
-As you can see, you are successively halving an array, which gives you the log(n) efficiency. For this challenge, we want you to show your work - how you got to the target value... the path you took!
+如你所見，你連續將數組減半，這爲你提供了 log(n) 效率。 對於這個挑戰，我們希望你展示你的工作——你是如何到達目標值的……你走過的路！
 
 # --instructions--
 
-Write a function `binarySearch` that implements the binary search algorithm on an array, returning the path you took (each middle value comparison) to find the target in an array.
+編寫一個函數 `binarySearch` 來實現對數組的二分查找算法，返回在數組中查找目標所採用的路徑（每個中間值比較）。
 
-The function takes a sorted array of integers and a target value as input. It returns an array containing (in-order) the middle value you found at each halving of the original array until you found the target value. The target value should be the last element of the returned array. If value not is found, return the string `Value Not Found`.
+該函數將一個排序的整數數組和一個目標值作爲輸入。 它返回一個數組，其中包含（按順序）你在原始數組的每個減半處找到的中間值，直到你找到目標值。 目標值應該是返回數組的最後一個元素。 如果未找到值，則返回字符串 `Value Not Found`。
 
-For example, `binarySearch([1,2,3,4,5,6,7], 5)` would return `[4,6,5]`.
+例如，`binarySearch([1,2,3,4,5,6,7], 5)` 將返回 `[4,6,5]`。
 
-For this challenge, when halving, you MUST use `Math.floor()` when doing division: `Math.floor(x/2)`. This will give a consistent, testable path.
+對於這個挑戰，當減半時，你必須在做除法時使用 `Math.floor()`：`Math.floor(x/2)`。 這將提供一致的、可測試的路徑。

-Binary search is an **O(log(n))** efficiency algorithm for searching a sorted array to find an element. It operates using the following steps:
+二分搜索是一种 **O(log(n))** 效率的算法，用于在已排序的数组以查找元素。 它通过以下步骤运行：
 
-1. Find the middle `value` of a sorted array. If `value == target` return (found it!).
-1. If middle `value < target`, search right half of array in next compare.
-1. If middle `value > target`, search left half of array in next compare.
+1. 查找已排序数组的中间值 `value`。 如果 `value == target`，则返回（找到了！）。
+1. 如果中间值 `value < target`，则在下一次比较中搜索数组的右半部分。
+1. 如果中间值 `value > target`，则在下一次比较中搜索数组的左半部分。
 
-As you can see, you are successively halving an array, which gives you the log(n) efficiency. For this challenge, we want you to show your work - how you got to the target value... the path you took!
+如你所见，你连续将数组减半，这为你提供了 log(n) 效率。 对于这个挑战，我们希望你展示你的工作——你是如何到达目标值的……你走过的路！
 
 # --instructions--
 
-Write a function `binarySearch` that implements the binary search algorithm on an array, returning the path you took (each middle value comparison) to find the target in an array.
+编写一个函数 `binarySearch` 来实现对数组的二分查找算法，返回在数组中查找目标所采用的路径（每个中间值比较）。
 
-The function takes a sorted array of integers and a target value as input. It returns an array containing (in-order) the middle value you found at each halving of the original array until you found the target value. The target value should be the last element of the returned array. If value not is found, return the string `Value Not Found`.
+该函数将一个排序的整数数组和一个目标值作为输入。 它返回一个数组，其中包含（按顺序）你在原始数组的每个减半处找到的中间值，直到你找到目标值。 目标值应该是返回数组的最后一个元素。 如果未找到值，则返回字符串 `Value Not Found`。
 
-For example, `binarySearch([1,2,3,4,5,6,7], 5)` would return `[4,6,5]`.
+例如，`binarySearch([1,2,3,4,5,6,7], 5)` 将返回 `[4,6,5]`。
 
-For this challenge, when halving, you MUST use `Math.floor()` when doing division: `Math.floor(x/2)`. This will give a consistent, testable path.
+对于这个挑战，当减半时，你必须在做除法时使用 `Math.floor()`：`Math.floor(x/2)`。 这将提供一致的、可测试的路径。

-One of the most powerful tools is your developer console. Depending on your browser, this might be opened by pressing `F12` or `Ctrl+Shift+I`. You can also click the "Console" button above the preview window to see our built-in console. The developer console will include errors that are produced by your code, but you can also use it to see values of variables in your code, which is helpful for debugging.
+Uma das ferramentas mais poderosas é o console do desenvolvedor. Dependendo do navegador, ele pode ser aberto pressionando `F12` ou `Ctrl+Shift+I`. Você também pode clicar no botão "Console" acima da janela de pré-visualização para ver o console embutido. O console do desenvolvedor incluirá erros produzidos pelo código, mas você também pode usá-lo para ver valores de variáveis no código, o que é útil para depuração.
 
-Add a `console.log("Hello World");` line between your `script` tags, then click the "Console" button to open our console, and you should see the text `Hello World` in your console.
+Adicione a linha `console.log("Hello World");` entre as tags `script` e, em seguida, clique no botão "Console" para abrir o console, e você deve ver ali o texto `Hello World`.
 
-Note how the line ends with a semi-colon. It is common practice in JavaScript to end your code lines with semi-colons.
+Observe como a linha termina com ponto e vírgula. É prática comum em JavaScript encerrar as linhas de código com ponto e vírgula.

-JavaScript offers the built-in `Math` utility which offers a number of mathematical tools. One of those is `Math.random()`, which generates a random number between 0 and 1. Another is `Math.floor()`, which rounds a given number down to the nearest integer.
+O JavaScript oferece o utilitário `Math` integrado, que oferece várias ferramentas matemáticas. Uma dessas é `Math.random()`, que gera um número aleatório entre 0 e 1. Outra é `Math.floor()`, que arredonda um número qualquer para o inteiro mais próximo abaixo dele.
 
-Using these, you can generate a random number within a range. For example, this generates a random number between 1 and 5: `Math.floor(Math.random() * 5) + 1;`.
+Ao usá-las, você pode gerar um número aleatório dentro de um intervalo. Por exemplo, isso gera um número aleatório entre 1 e 5: `Math.floor(Math.random() * 5) + 1;`.
 
-Following this pattern, add a random number between one and the value of `xp` at the end of your `monsterHealth` variable change.
+Seguindo este padrão, adicione um número aleatório entre um e o valor de `xp` no final da variável `monsterHealth`.

-We have run in to a slight problem. You are trying to query your page for a button element, but your `script` tag is in the `head` of your HTML. This means your code runs before the browser has finished reading the HTML, and your `document.querySelector()` will not see the button - because the browser hasn't processed it yet.
+Encontramos um pequeno problema. Você está tentando consultar a página para um elemento de botão, mas a tag `script` está no `head` do HTML. Isso significa que o código é executado antes de o navegador terminar de ler o HTML e `document.querySelector()` não verá o botão, pois o navegador ainda não o processou.
 
-To fix this, move your `script` element out of the `head` element, and place it at the end of your `body` element (just before the closing `</body>` tag.)
+Para corrigir isso, mova o elemento `script` para fora do elemento `head` e coloque-o no final do elemento `body` (logo antes da tag de fechamento `</body>`.)
