JavaScript 和 C# 之間的區別

Two programming languages that have been widely used in the field of software development are JavaScript and C# (pronounce "C sharp"). Both languages are employed for various purposes and sharp"). Both languages are employed for various purposes and each has its ownloyed advantages and disadvantages.

JavaScript程式語言的主要應用是建立網站。它經常用於建立動態和互動的網站。由於JavaScript是一種客戶端語言，它是在客戶端的瀏覽器中執行，而不是在伺服器上執行。它是初學者的流行選擇，因為它易於學習且入門門檻低。

On the other hand, C# is a popular object-oriented programming language for creating mobile apps, desktop programmes, and video games for Windows. Because it is a compiled language, the code must first be compil firtable in execuiled incuon table must first be compiled intiad in to be executed. Compared to JavaScript, C# is a more difficult language to learn and master.

What is C#?

微軟創建了現代物件導向的程式語言C#，發音為「C sharp」。自從它被創建出來，它經常被用來創建Windows桌面應用程式、遊戲和Web應用程序，因為它被設計成簡單、高效和易學。

The .NET Framework, a potent collection of tools and frameworks for creating Windows programmes, includes C#. It is a strongly-typed language, which implies that variables must be declared with a specified data type. requirement language's tight rules for variable usage, helps to eliminate typical programming errors.

Object-oriented programming is supported by C#, which makes it simple to create code that is structured, reusable, and simple to maintain. Moreover, functions like waste collection are supported. things conside, Cunctions like waste collection are supported。 that is frequently used for a wide range of applications.

C#的優勢

• 以物件導向的方式進行程式設計 − 因為C#是一種物件導向的語言，程式設計師可以建構和使用包含資料和方法的物件。

• 強型別檢查 − C#利用強型別檢查，可以在編譯時驗證型別的相容性。

• Extensive class library − The class library in C# offers a large selection of pre-built functions and data structures. Applications can now be developed more rapidly and effectiveively as#result.

C#的缺點

• Windows-centric − C# was created by Microsoft and is mostly utilised in environments that run Windows. Although it can run on other operating systems, those platforms might not be as optimised for ose platforms it.

• 對函數式程式設計的支援有限− 儘管C#是一種物件導向的語言，但它只包含了少量對函數式程式設計的支援。因此，對於一些嚴重依賴函數式程式設計的應用程式來說，它可能不是最理想的選擇。

• 垃圾回收 − 為了自動管理內存，C#採用了垃圾回收。儘管這對開發人員可能很有用，但不正確的使用可能會導致效能問題。

What is JavaScript?

The main application of the computer language JavaScript is the development of interactive and dynamic web sites. Brendan Eich developed it in 1995 while he was employed by Netscape Communications Corporation.

As a client-side language, JavaScript executes on the client's computer (usually in a web browser) as opposed to the server. Animations, form validation, and dynamic content updates are a few example qual exles interactivity to web sites.

Though JavaScript is a high-level language, it is made to be simple for people to read and write. Moreover, because it is an interpreted language, the code can be run immediately in the brow without the rement for compilation #t run immediately in the brow without the rement for compil.

##A number of in-built features in JavaScript make it a potent language for web development. They consist of regular expression, object, array, and function support. The Document Object Model (DOM) and the Browon lyObject are on ly aly couple of the APIs (application programming interfaces) that it has already been created with that enable interaction with web page elements (BOM).

JavaScript的優勢

• Client-side scripting

  − Scripting that is executed on the client side, such as JavaScript, does so in the browser and is not dependent on a server to function. The application runs faster as a result of less server load.

• 容易學習

  − JavaScript是一種使用者友善的語言，容易上手與理解。由於其簡單直觀的語法，與其他程式語言相似，因此適用於各種技能水平的開發人員。

• 互動性 - JavaScript可讓程式設計師能夠建立動態和互動的網站，可以即時回應使用者輸入。

Disadvantages of JavaScript

• Risks related to security − Cross-site scripting (XSS) attacks provide attackers the ability to steal user information or insert harmful code into a website. JavaScript is susceptible to these attacks.

• ##Browser compatibility − Because JavaScript acts differently in each browser, developers may encounter compatibility problems.

• Performance issues − Because JavaScript is an interpreted language rather than a compiled one like C or Java, it may run slower.

JavaScript與C#的差異

下表突顯了JavaScript與C#之間的主要差異−

JavaScript	C Sharp
JavaScript在大多數瀏覽器中運行，無需任何插件先決條件。	C# 需要一個外掛程式。
In a client machine, it is unable to browse or enter records.	#In the event that the specific 銀 光 version supports it, it can review and create records.
#JavaScript is dynamic written.	#Static written.
JavaScript has secluded libraries for doing in-person queries like underscore. js	Local querying can be done using the useful.NET component LINQ, which is available in C#.
There is no administrator or overburdening in JavaScript.	#C#有能力為管理員和變換帶來過重負擔。
Neither an administrator nor overburdening are present in JavaScript.	C#有廣泛的應用領域。
JavaScript的範圍有限，而且這種方言有一些缺點。	全球工程師選擇的一種非常強大的語言是C#。
JavaScript is a single threaded language.	C sharp supports multithreading.
JavaScript支援閉包腳本。	Closure script is not supported in C#.
伺服器端腳本由JavaScript支援。	C# does not have server side scripting capabilities.
The ".js" suffix is used to save JavaScript files.	".cs"副檔名用於儲存C#檔。

結論

總之，JavaScript和C#是兩種廣泛使用的程式語言，具有明顯的差異和特殊的優勢。 C#經常用於後端網頁開發和桌面應用程式開發，而JavaScript通常用於前端網頁開發。

JavaScript學習簡單，入門門檻低，而C#更難掌握，需要更高的能力。選擇這兩種語言之間的決策最終將取決於您專案的特定要求。
