Switch statements

Hello, consider the following code:

C#
int employeeLevel = 200;
string employeeName = "John Smith";

string title = "";

switch (employeeLevel)
{
    case 100:
        title = "Junior Associate";
        break;
    case 200:
        title = "Senior Associate";
        break;
    case 300:
        title = "Manager";
        break;
    case 400:
        title = "Senior Manager";
        break;
    default:
        title = "Associate";
        break;
}

Console.WriteLine($"{employeeName}, {title}");

C#
int employeeLevel = 200;
string employeeName = "John Smith";

string title = "";

switch (employeeLevel)
{
    case 100:
        title = "Junior Associate";
        break;
    case 200:
        title = "Senior Associate";
        break;
    case 300:
        title = "Manager";
        break;
    case 400:
        title = "Senior Manager";
        break;
    default:
        title = "Associate";
        break;
}

Console.WriteLine($"{employeeName}, {title}");

Can the switch expression be a expression that evaluates to true or false? like age < 5? or the case pattern can they be an expression that evaluates to true or false like age < 5?

Casting and Convert method in C#

Hello guys, sorry to disturb you all; I just have a little question. Consider the following:

C#
int num1 = 20;
num1 = (double) 20.0;

string num2 = "20";
num2 = (int) "20";

C#
int num1 = 20;
num1 = (double) 20.0;

string num2 = "20";
num2 = (int) "20";

My question is, notice that we can cast an int to a double (upcasting) or cast a double to an int (downcasting). But why can't we cast a string representing a number into an it? Why in such cases we should use the Convert.ToInt method? What is the difference between casting and convert?

{} vs [] when initializing an array in C#

Hello guys, is there a difference when we use {} to initialize an array or if we use [] ? I read that the [] is known as a collection expression.

C#

string[] orders = {"B123", "C234", "A345", "C15", "B177", "G3003", "C235", "B179"};

vs

string[] orders = ["B123", "C234", "A345", "C15", "B177", "G3003", "C235", "B179"];

C#

string[] orders = {"B123", "C234", "A345", "C15", "B177", "G3003", "C235", "B179"};

vs

string[] orders = ["B123", "C234", "A345", "C15", "B177", "G3003", "C235", "B179"];

Properties vs Fields in C#

Hello guys, can someone explain what is the difference between Properties and Fields in C# please. At first I thought that properties and fields were the same thing because they are accessed the same way, like writing person.name something like that. But this isn't the case. How do properties work? I noticed they work as method but they don't have any parentheses. They should be named the same way as the fields?

c#
public class Person
{
    private int age;  // Private field

    // Property: Combines getter and setter
    public int Age
    {
        get { return age; }              // Getter
        set
        {
            if (value >= 0)              // Validation
                age = value;             // Setter
        }
    }
}

c#
public class Person
{
    private int age;  // Private field

    // Property: Combines getter and setter
    public int Age
    {
        get { return age; }              // Getter
        set
        {
            if (value >= 0)              // Validation
                age = value;             // Setter
        }
    }
}

LINQ in C#

Hello guys, sorry to disturb you all; I'm currently learning about arrays. I noticed that we can query the array to return a new one using the following syntax: evenNumbers = numbers.Where(n => n % 2 == 0).ToArray(); I have one question. I understood that the ToArray() method is used to convert the filtering result into an array. But what if we omit it? What would happen? What would evenNumber store? Would we be able to access the filtered values?

Data types in C#

Hi guys, I'm currently learning C# with microsoft learn. I read elsewhere that C# contains 2 types of data types, primitive and referenced. I have a small background in Java. In java, we use the capitalized the first letter of any referenced data type because they are classes, like String. So, I was wondering if this is different in C#... I noticed that we declare a variable of type string as: string varName where the s is in lowercase.

Trying to understand the basics of C# and .NET

Hello guys, sorry to disturb you all; I'm current learning C#l; I just started so I'm trying to understand some basic things first. From what I have understood, C# is a programming language built on top of the .NET framework. C# is widely used because of its libraries/community support which help in the development of games, web services, desktop app etc... (please correct me if I'm wrong). Now when we run a C# code, our code isn't directly run/translated into machine code. What happens, is at runtime (when we run the code), our source code is compiled into an intermediate language (in java I know we refer it to as bytecode, here what is its technical name please). This compilation is done by a virtual machine known as the CLR, common language runtime virtual machine. After compilation, this intermediate code is then translated into machine code and executed. This make C# platform independent meaning we can run it on any OS we want. Now I have came across 2 things, the Garbage collector and Just-In Time Compilation (JIT). I know that Garbage collector is that "free" memory (RAM) when required. But what about the JIT please; what is its use, why is it useful. I don't have a good understanding of JIT, would really appreciate if someone can explain pls.

Axios vs Fetch

Hello guys, sorry to disturb you all; I was just reading a bit about the difference between axios and fetch. From what I have understood, some of the differences is that axios already parse the data in the respond body and so we don't have to manually use something like response.json(). Similarly, when using post requests, axios don't need to include the JSON.stringify() method. By default it already does it. It also has some other benefits like a timeout argument which fetch doesn't have (I think). My question is, I came across the term "interceptors". I read a bit about it, from what I have understood, it's just something use to modify the request before it is send or modify the response before it is sent back. But I didn't really understand why are interceptors used or why do we need it . Can someone explain please

Understanding sessions in express

Hello guys, sorry to disturb you all; I'm currently learning about managing sessions in express and I came across 2 properties: resave and saveUninitialized. I didn't understand these 2 properties; where and why do we use them? What does they do? From what I have understand, resave prevents the session from storing data for each request in our store (but what if we don't use a store? Like in my case; when is a store needed?) while saveUninitialized just makes sure that we create a cookie if we modify the request session
