The life cycle of a Lightning Web Component (LWC) includes creation, rendering, updating, and destruction.

• 1. Creation: LWC is created when it is inserted into the DOM.

• 2. Rendering: LWC's template is rendered to the DOM.

• 3. Updating: LWC updates when its properties or state change.

• 4. Destruction: LWC is destroyed when removed from the DOM.

Recursion in LWC is triggered by calling a function within itself, and it is handled by setting a base case to prevent infinite loops.

• Recursion in LWC is triggered when a function calls itself within its own code.

• To handle recursion, a base case is set to stop the function from infinitely calling itself.

• Example: A recursive function in LWC that calculates factorial of a number by calling itself with decrementing input until reaching 1.

Programs for generating prime numbers and swapping two numbers.

• For generating prime numbers, iterate through numbers and check if they are divisible by any number less than them.

• For swapping two numbers, use a temporary variable to store one of the numbers before swapping them.

• Both programs can be implemented using loops and conditional statements.

Broadcast is a method of sending a message to multiple recipients, while accumulator is a variable that stores the result of an operation.

• Broadcast sends a message to multiple recipients simultaneously.

• Accumulator is a variable that stores the result of an operation by continuously adding or accumulating values.

• Example: Broadcasting a message to all users in a chat group vs. using an accumulator to sum up numbers in a loop.

Stored procedures are precompiled SQL queries that can perform multiple operations, while functions are reusable code blocks that return a single value.

• Stored procedures can execute multiple SQL statements, while functions can only return a single value.

• Stored procedures can have input and output parameters, while functions can only have input parameters.

• Stored procedures can be used to perform complex operations like transactions, while functions are typically used for calcu...read more

State management refers to the process of storing and retrieving data related to the state of an application.

• It involves managing the data that is required to maintain the state of an application.

• State can be stored on the client-side or server-side depending on the application architecture.

HTTP health checkup in K8s is a way to monitor the health of applications running in Kubernetes clusters.

• HTTP health check is a method to periodically check the health of an application by sending HTTP requests to a specified endpoint.

• In Kubernetes, you can define HTTP health checks in the pod's configuration using readiness and liveness probes.

• Readiness probes are used to determine when a pod is ready to serve traffic, while liveness probes are used to determine if a pod is ...read more
