Class/Record/Struct

 

FeatureClassRecordStruct
TypeReference TypeReference Type (since C# 10, can be record struct)Value Type
Memory AllocationTypically allocated on the heap.Typically allocated on the heap.Typically allocated on the stack (or heap if used as part of a class or array)
Default ConstructorCan have a parameterless constructor, and can be explicitly defined.Implicit parameterless constructor is not allowed; parameters are required.Parameterless constructor is provided by default and initializes all fields to default values.
InheritanceSupports inheritance (can inherit from other classes and be inherited).Supports inheritance (can inherit from other records but not from classes).Does not support inheritance (cannot inherit from or be inherited by other types).
EqualityUses reference equality by default, can override Equals and GetHashCode for value-based equality.Uses value-based equality by default (based on all properties). Automatically implements Equals, GetHashCode, and ToString.Uses value-based equality by default (based on all fields). Automatically implements Equals, GetHashCode, and ToString.
MutabilityMutable by default; properties can be changed after object creation.Immutable by default; properties are readonly and set via constructor.Immutable by default (properties are typically readonly and initialized in the constructor).
DeconstructionNot supported by default.Supports deconstruction with tuple-like syntax.Supports deconstruction with tuple-like syntax.
ConstructorCan have multiple constructors with various parameters.Primary constructor is defined with positional parameters; can also have additional constructors.Constructor must initialize all fields; no parameterless constructor allowed unless provided by the compiler.
Default ValuesFields initialized to default values if not explicitly set.Properties are initialized via the constructor.Fields are initialized to default values (e.g., 0, null).
Use CasesUsed for complex objects with behavior and mutable state.Ideal for immutable data models, DTOs, and scenarios where value-based equality is important.Ideal for lightweight, immutable data structures where copying and stack allocation are beneficial.

Angular Basics

Intro

    package.json

     (list of dependencies)

    package-lock.json

     (details list of that dependencies)

    angular.json

     (map everything here: assets, scripts etc)

    tsconfig.json

     (typescript configuration file)

    polyfills.ts

     (compatibility file)

 

Components

    Modules must be declared in the imports

    Components must be declared in the declarations

    Standalone components are not dependent in any modules and it must be declared in imports

    and Pipes are doing the transformation over text


Bindings - Two Way, Property, Event


Routing

    Basic Routing

      Routes for mapping path & component

      routerLink navigate to different routes

      router-outlet for displaying matched route

    Child routing

     Activated Route (const routeId = route.snapshot.paramMap.get(id);)

    Module Routing

     const routes : Routes

    Lazy Loading

     Load when required (loadChildren then import)


Directives

    Add additional behavior to elements

    Components works as a directive

    Attribute Directive

ngClass (Binding Classes)

ngStyle (Binding Styles, Only accept objects s = {})

ngModel (Two Way Binding)

    Structural Directive

*ngIf

*ngFor

*ngSwitch


Services

    Defined with @Injectable

    All are in observable format and without subscribe it wont work (Rxjs feature)


FormType

    TDF handle in html file

     ngForm

    Reactive handle in ts file

     FormGroup


Guard

    used to control access in particular route

    canActivate

    canActivateChild

    canDeactivate

    canLoad


Interceptor

    Used for token login

    Declares in app.module [Providers]


Rxjs

    Observable and Operators

    Promise (then, then, finally)
