How exactly data binding in LWC works?
Let's understand the concept of reactivity in LWC
Decorators in LWC
What are decorators and diff decorators available in LWC?
Let me show you how we can use API decorators to expose a function
Let's move on to the next decorator which is @wire decorator
The last and most important decorator and that is @track decorator
Different ways to invoke APEX from LWC
Let us source the output of the Apex method to the client-side controller using a wire decorator 1/2
Let us source the output of the Apex method to the client-side controller using a wire decorator 2/2

Events in LWC
Let's do some hands-on on events in JavaScript
Let us look at events in LWC using bubbling configuration
What if I want the event to cross the shadow boundary?
So, what is the most frequently used configuration while working with events in LWC?

How to implement navigation in LWC?
Lightning Message Service
How can we share data between components when they are not in hierarchy? LMS is the answer.
Initially, we need to create a Lightning message channel
Then comes the publisher, let's create it
And then we need to create a subscriber so that we can start receiving the updates
How can we replicate the same thing between Aura components?
Let's refactor the code of publisher and subscriber a bit
And what if I want to replicate the same thing between Visualforce pages?
Exposing Lightning Web Components
Where all can we expose a Lightning web component?
Lighting Data Service [LDS]
For the same tag, let's make the record ID and content dynamic
Now let's work on giving the visual confirmation to the user using the ShowToastEvent
Let's override the standard functionality using the Lightning Data Service.
Let's use the ShowToastEvent to show an error message
Let's look at the all-in-one tag <lightning-record-form />
What if I want to display a customized fields set on the UI using Lightning Record Form tag?
Let me walk you through the createRecord() method in LDS 1/2
Let me walk you through the createRecord() method in LDS 2/2
Let me walk you through the updateRecord method in LDS 1/2
Let me walk you through the updateRecord() method in LDS 2/2
What if I want to delete a record using LDS? Is it possible?
Let's look at getRecord in LDS 1/2
