Go supports object-oriented programming principles through struct types and methods.
Go uses struct types to define objects with fields and methods.
Methods can be defined on struct types to provide behavior to objects.
Go does not have classes like traditional OOP languages, but it supports encapsulation, inheritance, and polymorphism through struct embedding and interfaces.
Arrays are fixed-size collections of elements of the same type, while slices are dynamic arrays with a flexible size.
Arrays have a fixed size determined at compile time.
Slices are dynamic arrays that can grow or shrink.
Arrays and slices are both zero-indexed.
Arrays are passed by value, while slices are passed by reference.
Example: var arr [3]string = [3]string{"apple", "banana", "orange"}
Example: var slice []string = [
Goroutines are lightweight threads managed by Go runtime, allowing concurrent execution of functions.
Goroutines are created using the 'go' keyword followed by a function call.
They are multiplexed onto multiple OS threads by the Go runtime.
Goroutines communicate using channels to share data safely.
They are more efficient than traditional threads due to their lightweight nature.
Go is simpler, more efficient, and easier to learn compared to C++.
Go has a simpler syntax and is easier to read and write compared to C++.
Go has built-in concurrency support with goroutines and channels, making it easier to write concurrent programs.
Go has a garbage collector, which simplifies memory management compared to manual memory management in C++.
Go compiles faster than C++ due to its simpler type system and l...

Routes are defined using the RouterModule.forRoot() method
Each route maps a URL path to a component
RouterLink directive is used to navigate between routes in HTML
Router.navigate() method is used to navigate programmatically
Child routes can be defined for nested comp

Concurrency is the ability of a program to execute multiple tasks simultaneously. Race condition occurs when multiple threads access shared data and try to change it at the same time.
Concurrency allows multiple tasks to run in parallel, improving performance and efficiency.
Race condition happens when multiple threads access and modify shared data without proper synchronization.
To prevent race conditions, synchronizatio...
