 المثال السابق لم يكن به أي عمليات معقدة ولكن دالة `splice` غيرت القائمة الأصلية، وأسفرت عن حدوث خطأ.
 
-تذكر أنه في البرمجة الوظيفية، تغيير الأشياء يسمى طفرة <dfn>mutation</dfn>، وتسمى النتيجة تأثير جانبي <dfn>side effect</dfn>. من الناحية المثالية، يجب أن تكون الوظيفة <dfn>pure function</dfn>، مما يعني أنها لا تسبب أي تأثيرات جانبية.

 حاول أن تتقن هذا النظام وألا تغير أي متغير أو كائن في التعليمات البرمجية.

 في D3، هناك مقاييس للمساعدة في ملأ البيانات. تكون `scales` وظائف (functions) تخبر البرنامَج كيفية ملأ مجموعة من نِقَاط البيانات الخام على البكسلات (px) في لوحة SVG.
 
-على سبيل المثال، قل أن لديك لوحة SVG بحجم 100x500، وأنت تريد ملأ الناتج إجمال المحلي (Gross Domestic Product) لعدد من الدول. The set of numbers would be in the billion or trillion-dollar range. You provide D3 a type of scale to tell it how to place the large GDP values into that 100x500-sized area.
+على سبيل المثال، قل أن لديك لوحة SVG بحجم 100x500، وأنت تريد ملأ الناتج إجمال المحلي (Gross Domestic Product) لعدد من الدول. ومجموعة الأعداد ستكون في حدود المليار أو تريليون دولار. يمكنك توفير D3 من المقياس لمعرفة كيفية وضع قيم الناتج المحلي الإجمالي الكبيرة في تلك المساحة 100x500.
 
-It's unlikely you would plot raw data as-is. Before plotting it, you set the scale for your entire data set, so that the `x` and `y` values fit your canvas width and height.
+من غير المحتمل أن تملأ البيانات الخام كما هي. قبل الملأ، عيّن المقياس لكامل مجموعتك للبيانات. بحيث أن قيم `x` و `y` تتناسب مع عرض وطول اللوحة.
 
-D3 has several scale types. For a linear scale (usually used with quantitative data), there is the D3 method `scaleLinear()`:
+ولدى D3 عدة أنواع من المقاييس. للحصول على مقياس خطي (linear scale) (يستخدم عادة مع البيانات الكمية (quantitative data))، هناك طريقة في D3 تسمى `scaleLinear()`:
 
 ```js
 const scale = d3.scaleLinear()
 ```
 
-By default, a scale uses the identity relationship. The value of the input is the same as the value of the output. A separate challenge covers how to change this.

These functions are executed when some event happens (e.g. someone hits an endpoint on your API). We’ll follow the same approach in these exercises. The `done()` function is a callback that tells us that we can proceed after completing an asynchronous operation such as inserting, searching, updating, or deleting. It's following the Node convention, and should be called as `done(null, data)` on success, or `done(err)` on error.

 Currently, you cannot determine who is connected to your web socket. While `req.user` contains the user object, that's only when your user interacts with the web server, and with web sockets you have no `req` (request) and therefore no user data. One way to solve the problem of knowing who is connected to your web socket is by parsing and decoding the cookie that contains the passport session then deserializing it to obtain the user object. Luckily, there is a package on NPM just for this that turns a once complex task into something simple!

Se hai dei dati tabulari, puoi usare un oggetto per cercare valori piuttosto che un'istruzione `switch` o una catena `if/else`.

-Before you start diving in to the table itself, your `span` elements are currently bolded. Create a `span:not(.sr-only)` selector and give it a `font-weight` property set to `normal`.
+テーブル自体のスタイル設定に取り掛かりたいところですが、現状、`span` 要素が太字になっています。 `span:not(.sr-only)` セレクターを作成して、`font-weight` プロパティを `normal` に設定してください。
 
-The `:not()` pseudo-selector is used to target all elements that do not match the selector - in this case, any of your `span` elements that do not have the `sr-only` class. This ensures that your earlier rules for the `span[class~="sr-only"]` selector are not overwritten.
+`:not()` 疑似セレクターを使うと、あるセレクターに一致しないすべての要素を選択できます。この例では、`sr-only` クラスを持たない `span` 要素すべてを選択します。 これで、前に設定した `span[class~="sr-only"]` クラス用のルールが上書きされなくなります。
