ES6 features are modern JavaScript enhancements that improve code readability and efficiency.
Arrow functions for concise syntax: const add = (a, b) => a + b;
Let and const for block-scoped variables: let x = 5; const y = 10;
Template literals for string interpolation: const name = 'John'; console.log(`Hello, ${name}!`);
Destructuring assignment for easily extracting values from arrays or objects: const { firstName, las...
Shallow copy only copies the references of nested objects, while deep copy creates new copies of nested objects.
Shallow copy creates a new object but does not create copies of nested objects.
Deep copy creates a new object and also creates copies of nested objects.
Shallow copy is faster and more memory efficient, but changes to nested objects affect both original and copied objects.
Deep copy is slower and consumes more ...
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
BehaviourSubject requires an initial value when created
Custom pipes in Angular are used to transform data in templates.
Custom pipes are created using the @Pipe decorator in Angular.
To use a custom pipe in HTML, you need to include it in the declarations array of the NgModule.
You can pass parameters to custom pipes in HTML using the pipe symbol (|).
Example: {{ value | customPipe:param1:param2 }}
ng-template, ng-content, and ng-container are Angular structural directives used for template rendering and content projection.
ng-template is used to define a template that can be rendered conditionally or multiple times.
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

A data structure that stores a sequence of elements in a linear order.
Consists of nodes that contain data and a pointer to the next node.
Can be singly linked or doubly linked.
Used for implementing stacks, queues, and hash tables.
Example: Singly linked list - 1 -> 2 -> 3 -> null
Example: Doubly linked list - null <- 1 <-> 2 <-> 3 -> null
VLAN works under the principle of network segmentation.
VLAN separates a physical network into multiple logical networks.
It improves network performance, security, and management.
VLAN tags packets with a unique identifier to identify the network they belong to.
Example: VLAN can be used to separate guest and employee networks in a company.
