-In the first two lines of the file `myApp.js`, you can see how easy it is to create an Express app object. This object has several methods, and you will learn many of them in these challenges. One fundamental method is `app.listen(port)`. It tells your server to listen on a given port, putting it in running state. For testing reasons, we need the app to be running in the background so we added this method in the `server.js` file for you.

PATH is a relative path on the server (it can be a string, or even a regular expression). HANDLER is a function that Express calls when the route is matched.

-`Versions` of the npm packages in the dependencies section of your package.json file follow what’s called Semantic Versioning (SemVer), an industry standard for software versioning aiming to make it easier to manage dependencies. Libraries, frameworks or other tools published on npm should use SemVer in order to clearly communicate what kind of changes projects can expect if they update.
+تتبع القيم في `Versions` من حزم npm في قسم التبعيات من الحُزْمَة الخاصة بك. النظام الذي يسمى بالإصدار الدلالي لنُسخ البرمجيات Semantic Versioning (SemVer)، وهو نمط صناعي لإصدار البرامج يهدف إلى تيسير إدارة الاعتمادات. كل من المكتبات، أو الأطر أو الأدوات الأخرى المنشورة على npm ينبغي أن تستخدم SemVer من أجل الإبلاغ بوضوح عن نوع التغييرات التي يمكن أن تتوقعها المشروعات إذا تم تحديثها.
 
-Knowing SemVer can be useful when you develop software that uses external dependencies (which you almost always do). One day, your understanding of these numbers will save you from accidentally introducing breaking changes to your project without understanding why things that worked yesterday suddenly don’t work today. This is how Semantic Versioning works according to the official website:
+معرفة SemVer مفيدة عند تطوير البرامج التي تستخدم التبعية الخارجية (التي تكاد تقوم بها دائما). يوما ما، فهمك لهذه الأرقام سوف يحفظك من إدخال تغييرات على مشروعك عن طريق الخطأ دون تفهم لماذا لا تعمل فجأة اليوم الأشياء التي عملت بالأمس. هذه هي الطريقة التي تعمل بها Semantic Versioning وفقا للموقع الرسمي على الإنترنت:
 
 ```json
 "package": "MAJOR.MINOR.PATCH"
 ```
 
-The MAJOR version should increment when you make incompatible API changes. The MINOR version should increment when you add functionality in a backwards-compatible manner. The PATCH version should increment when you make backwards-compatible bug fixes. This means that PATCHes are bug fixes and MINORs add new features but neither of them break what worked before. Finally, MAJORs add changes that won’t work with earlier versions.
+يجب أن يزداد رَقَم الإصدار MAJOR عند إجراء تغييرات API غير متوافقة. يجب أن يزداد رَقَم إصدار MINOR عند إضافة وظيفة بطريقة متوافقة رجعياً. يجب أن يزداد رَقَم الإصدار PATCH عند إجراء تصليحات للأخطاء متوافقة رجعيا. وهذا يعني أن PATCHES هي إصلاحات للأخطاء و MINORs تضيف ميزات جديدة ولكن كلا منهما لا يكسر ما كان يعمل من قبل. وأخيراً، يضيف MAJORs تغييرات لن تعمل مع الإصدارات السابقة.

-You have now tested a few ways you can manage dependencies of your project by using the package.json's dependencies section. You have also included external packages by adding them to the file and even told npm what types of versions you want, by using special characters such as the tilde or the caret.
+لقد اختبرت الآن بعض الطرق الذي يمكنك بها إدارة التبعيات لمشروعك باستخدام قسم التبعيات في package.json. لقد قمت أيضا بإدراج حزم خارجية عن طريق إضافتها إلى الملف وأخبرت npm ما هي أنواع الإصدارات التي تريدها، باستخدام أحرف خاصة مثل tilde (~) أو caret (^).
 
-But what if you want to remove an external package that you no longer need? You might already have guessed it, just remove the corresponding key-value pair for that package from your dependencies.
+ولكن ماذا لو أردت إزالة حزمة خارجية لم تعد بحاجة إليها؟ ربما قد خمنتها فعلًا، عليك فقط أن تزيل زوج key-value المقابل لتلك الحزمة من تبعياتك (dependencies).
 
-This same method applies to removing other fields in your package.json as well.
+تنطبق نفس الطريقة على إزالة الخانات الأخرى في package.json أيضا.
 
 # --instructions--
 
-Remove the `@freecodecamp/example` package from your dependencies.
+أزل حزمة `@freecodecamp/example` من تبعياتك.
 
-**Note:** Make sure you have the right amount of commas after removing it.

-Similar to how the tilde we learned about in the last challenge allows npm to install the latest PATCH for a dependency, the caret (`^`) allows npm to install future updates as well. The difference is that the caret will allow both MINOR updates and PATCHes.
+شبيهة بالطريقة التي تعلمنا بها عن tilde في التحدي الأخير وكيف يسمح لـ npm بتثبيت أحدث PATCH للاعتماد، يسمح رمز caret (`^`) إلى npm تثبيت التحديثات المستقبلية أيضًا. إن الفرق سيسمح رمز caret لكل من التحديثات من MINOR و PATCH.
 
-Your current version of `@freecodecamp/example` should be "~1.2.13" which allows npm to install to the latest 1.2.x version. If you were to use the caret (^) as a version prefix instead, npm would be allowed to update to any 1.x.x version.
+يجب أن يكون إصدار `@freecodecamp/example` الخاص بك الحالي من "~1.2.13" الذي يسمح npm بتثبيت أحدث إصدار 1.2.x. إذا كنت ستستخدم caret (^) كبادئة إصدار بدلاً من ذلك، سيسمح لـ npm بالتحديث إلى أي إصدار x.x.1.
 
 ```json

-In the last challenge, you told npm to only include a specific version of a package. That’s a useful way to freeze your dependencies if you need to make sure that different parts of your project stay compatible with each other. But in most use cases, you don’t want to miss bug fixes since they often include important security patches and (hopefully) don’t break things in doing so.
+في التحدي الأخير، أخبرت npm أن يتضمن نسخة محددة فقط من الحزمة. هذه طريقة مفيدة لتجميد التبعية إذا كنت بحاجة إلى التأكد من أن أجزاء مختلفة من مشروعك تبقى متوافقة مع بعضها البعض. ولكن في معظم حالات الاستخدام، لا ترد أن تفوتك إصلاحات الأخطاء لأنها غالباً ما تتضمن التصحيحات الأمنية الهامة ومن الآمل أنها لا تتسبب لتخريب تطبيقك بذلك.
 
-To allow an npm dependency to update to the latest PATCH version, you can prefix the dependency’s version with the tilde (`~`) character. Here's an example of how to allow updates to any 1.3.x version.
+للسماح للتبعية npm للتحديث إلى أحدث إصدار PATCH، يمكنك أن تضيف رمز (`~`) في بداية الإصدار للتبعية. إليك مثال على كيفية السماح بالتحديثات لأي إصدار 1.3.x.
