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.

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.

Kubernetes is a container orchestration tool that manages containerized applications across multiple hosts, while Docker Swarm is a clustering and scheduling tool for Docker containers.

• Kubernetes is more feature-rich and complex, offering advanced features like auto-scaling, self-healing, and rolling updates.

• Docker Swarm is simpler to set up and use, making it a good choice for smaller deployments or users familiar with Docker.

• Kubernetes has a larger community and ecosystem, ...read more

Azure IR stands for Azure Integration Runtime, which is a data integration service in Azure Data Factory.

• It allows data movement between cloud and on-premises data sources.

• Azure IR supports activities like data copy, data flow, and data transformation.

• It can be configured to run in different modes such as Azure, Self-hosted, and Azure-SSIS.

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
