Arrow functions are concise and do not bind their own 'this' value, while regular functions have their own 'this' value and can be used as constructors.
Arrow functions have a more concise syntax compared to regular functions.
Arrow functions do not have their own 'this' value, they inherit it from the parent scope.
Regular functions have their own 'this' value, which can be useful for object-oriented programming and cons
Subject vs BehaviourSubject in Angular
Subject is a basic observable that emits values to subscribers
BehaviourSubject is a type of Subject that stores the latest value and emits it to new subscribers

Custom pipes in Angular are used to transform data in templates.
Custom pipes are created using the @Pipe decorator in Angular.

You can pass parameters to custom pipes in HTML using the pipe symbol (|).
Example: {{ value | customPipe:param1:param2 }}

ng-content is used for content projection, allowing the insertion of content from a parent component into a child component.
ng-container is a grouping element that doesn't interfere with styles or layo...
ForkJoin is an operator in Angular that allows for parallel execution of multiple observables.
ForkJoin combines the values from multiple observables and emits them as an array when all observables complete.
It waits for all observables to complete and then emits the combined result.
Example: forkJoin([observable1, observable2]).subscribe(result => console.log(result));
Wildcard routes in Angular allow for handling unknown routes and redirecting to a default route.
Wildcard route is denoted by '**' in the route configuration.
It is typically used at the end of the route configuration to handle unknown routes.
Example: { path: '**', redirectTo: '/404' }
Handle errors in fetching API calls by implementing error handling mechanisms.
Use try-catch blocks to catch errors during API calls
Implement error handling logic in the catch block to handle different types of errors
Display user-friendly error messages to inform users about the issue
Use HTTP status codes to identify the type of error (e.g. 404 for not found)
Implement retry mechanisms for temporary network issues
