Two way binding in Angular allows automatic synchronization of data between the model and the view.
Two way binding is achieved using the ngModel directive.
Changes made in the view are automatically reflected in the model and vice versa.
It simplifies the code and reduces the need for manual event handling.
Example:
Synchronous data in Node.js can be handled using callbacks or promises.
Use callbacks to handle synchronous data in Node.js
Promises can also be used to handle synchronous data
Avoid using synchronous code in Node.js as it can block the event loop
Node is asynchronous, meaning it can handle multiple requests at once without blocking the main thread.
Node uses an event-driven, non-blocking I/O model
Callbacks are used to handle asynchronous operations
Example: Reading a file using fs module
Example: Making an HTTP request using http module
MongoDB is better suited for handling unstructured data and offers better scalability and performance compared to MySQL.
MongoDB is a NoSQL database that allows for flexible and dynamic schema design.

A callback is a function passed as an argument to another function, which is then invoked inside the outer function.
Callbacks are used to execute code asynchronously, such as when an event occurs or when data is retrieved from a server.
They are commonly used in JavaScript for event handling, AJAX requests, and timers.
Callbacks can also be used for error handling, allowing the caller to handle errors that occur ins...
Observables are a way to handle asynchronous data streams in Angular.
Observables are similar to Promises but can emit multiple values over time.
They can be created using the RxJS library.
They are often used for handling HTTP requests and real-time data updates.
Operators can be used to transform, filter, and combine observables.
Subscriptions are used to listen to the emitted values and handle errors and completion.

CRUD stands for Create, Read, Update, and Delete. It refers to the basic operations performed on a database.
Create - inserting new data into the database
Read - retrieving data from the database
Update - modifying existing data in the database
Delete - removing data from the database
CRUD operations are essential for managing data in a database
Examples include adding a new user, updating a product's price, or deleting a cu...

A bit is the smallest unit of data in computing, representing a binary value of 0 or 1.
A bit can represent two states: off (0) or on (1).
Bits are the building blocks of all digital data, including text, images, and sound.
In binary code, a sequence of bits can represent numbers, letters, and commands.
For example, the letter 'A' is represented as 01000001 in binary, which is 65 in decimal.
A bit is the smallest unit of digital information. It can have a value of either 0 or 1.
A bit is a binary digit, represented as either 0 or 1.
It is the basic unit of information used in computing and digital communications.
A group of 8 bits is called a byte.
The size of a bit is dependent on the architecture of the computer system.
C is a programming language and does not have a fixed number of bits.
C is a high-level programming language that can be compiled to run on different architectures with varying bit sizes.
The number of bits in C depends on the hardware architecture it is compiled for.
For example, C code compiled for a 32-bit architecture will have 32-bit integers, while code compiled for a 64-bit architecture will have 64-bit integers.
