Difference Between Javascript And C#

In the realm of programming, two primary programming languages commonly employed in software development are JavaScript and C#. While they share some similarities, each possesses distinct traits, capabilities, and applications. Programmers need to grasp these differences when choosing between them for specific projects. Let's delve deeper into these variances.

Overview:

JavaScript:

JavaScript is a dynamic, interpreted, high-level programming language commonly employed in web development. Initially conceived by Brendan Eich in 1995 to enhance web page interactivity, it has evolved into a versatile language suitable for front-end as well as back-end development purposes.

It is commonly referred to as "C sharp". C# is a statically typed, general-purpose programming language introduced by Microsoft and incorporated into the .NET framework. Designed under the guidance of Anders Hejlsberg, it was first introduced in 2000 as a tool for developing reliable, cross-platform applications.

Syntax and Structure:

JavaScript:

JavaScript shares a syntax that closely resembles C, making it easy for developers familiar with C or Java to grasp. Its flexible nature allows for variable declaration and manipulation with permissive typing. JavaScript also follows prototypal inheritance and utilizes curly braces to define blocks of code.

Example:

Let's consider a JavaScript script that computes the total of numbers ranging from 1 to a specified value.

function calculateSum(num) {
 let sum = 0;
 for (let i = 1; i <= num; i++) {
 sum += i;
 }
 return sum;
}

const inputNumber = 5;
const result = calculateSum(inputNumber);
console.log(`The sum of numbers from 1 to ${inputNumber} is: ${result}`);

Output:

The <style> element's CSS properties are styled as follows:

.placeholder-diagram { The background is set as a linear gradient with a color transition from #374151 to #1f2937, a border radius of 12px, padding of 40px, a top and bottom margin of 20px, and aligned centrally. }

.placeholder-diagram .placeholder-icon { The font size is 3rem with a margin at the bottom of 10px. }

.placeholder-diagram .placeholder-text { The text color is #9ca3af with a font size of 1rem. }

Explanation:

The code is explained below:

• ✅ The calculateSum function in this JavaScript program accepts an input number as a parameter, num.
• ✅ A variable called sum is initialized to zero inside the function.
• ✅ It adds each iteration value of i to the sum variable using a for loop that runs from 1 up to the specified num.
• ✅ The calculated total is returned by the loop once it has finished.
• ✅ A constant variable called inputNumber with the value 5 is declared in the main section.
• ✅ The result is stored in the variable result when the calculateSum function is called with inputNumber as an argument.
• ✅ Lastly, a message displaying the computed sum of the numbers from 1 to inputNumber is logged to the console using console.log.

Employing a syntax reminiscent of C and C++, C# provides a structured and object-oriented method for coding. As a statically typed language, explicit declaration of variable types is necessary. C# follows a class-based inheritance system and delineates blocks with braces.

Example:

Let's consider a C# program to determine the factorial of a given number.

using System;
class Program
{
 static void Main()
 {
 Console.Write("Enter a number to calculate its factorial: ");
 int num = Convert.ToInt32(Console.ReadLine());
 int factorial = CalculateFactorial(num);
 Console.WriteLine($"The factorial of {num} is: {factorial}");
 }
 static int CalculateFactorial(int number)
 {
 if (number == 0 || number == 1)
 {
 return 1;
 }
 else
 {
 int result = 1;
 for (int i = 2; i <= number; i++)
 {
 result *= i;
 }
 return result;
 }
 }
}

Output:

The CSS code snippet displayed below creates a placeholder diagram with a stylish design. The diagram features a linear gradient background with a color scheme of #374151 and #1f2937. It has a border-radius of 12px, padding of 40px, and a margin of 20px at the top and bottom. The content within the diagram is centered for a neat appearance. Additionally, the placeholder includes an icon with a font size of 3rem and some text with a font size of 1rem in a color of #9ca3af.

Explanation:

The program is explained as below:

• ✅ The user is prompted by the program to enter a number.
• ✅ It uses Console to read the user input as an integer Convert.ToInt32 with ReadLine .
• ✅ Using a loop, the CalculateFactorial method determines the factorial of the input number.
• ✅ The procedure returns 1 (factorial of 0 or 1 is 1) if the input number is 0 or 1.
• ✅ The method multiplies the result by each integer from 2 to the specified value using a for loop after initializing a result variable to 1.
• ✅ The factorial variable contains the computed factorial.
• ✅ Lastly, the application uses the WriteLine to show the calculated factorial.

Use Cases:

There are various applications for JavaScript and C#. Some primary examples of the use cases for both JavaScript and C# include:

JavaScript:

JavaScript is primarily utilized in web development, where it powers interactivity on websites by enabling features such as animations, form validation, and dynamic content updates. With the advent of Node.js, developers can now create full-stack applications using JavaScript for server-side development as well.

C# finds extensive use across various domains, including enterprise-grade software within the .NET framework, web programming using ASP.NET, game creation using Unity, and building desktop applications like Windows Forms and WPF. It is notably favored for its application in Windows software development.

Platform and Ecosystem:

JavaScript:

JavaScript is extensively utilized in web development due to its compatibility with all modern web browsers. Its broad range of libraries and frameworks such as Angular, Vue.js, and React contribute to an extensive environment that enhances both its front-end and back-end development functionalities.

C# is a popular choice for developing applications on Windows due to its close integration with the .NET framework. Nevertheless, C# applications have expanded their compatibility to include multiple platforms such as Windows, macOS, and Linux, thanks to the evolution of .NET Core into .NET 5 and subsequent iterations.

Conclusion:

In summary, despite some syntactic resemblances, JavaScript and C# cater to different programming sectors. JavaScript is widely used in web development as it offers adaptability and versatility for tasks in both front-end and back-end domains. Conversely, C# is highly effective in creating robust applications across various platforms, especially within the Windows ecosystem, thanks to its integration with .NET.

When deciding between JavaScript and C#, the choice boils down to the project requirements, preferred platform, and the developer's familiarity and inclinations. Understanding the unique benefits and applications of each language is crucial for selecting the most suitable tool for software development endeavors.
