Why do we use LWC?
Lightning Web Components (LWC) is a stack of modern lightweight frameworks built on the latest web standards. It is a DOM (Document Object Model), element created through reusable code and is used to generate a dynamic interface without using JavaScript or building a Library.
Which resources can be included in a lightning component bundle?
The bundle contains all the required resources related to a component like javascript controller, javascript helper, renderer, CSS styles, etc. A basic lightning component contains the design of a page in Html with some lightning tags. The component uses JavaScript on the client-side and Apex on the server-side.
What is the use of the Aura method tag in lightning?
We Use <aura:method> to define a method as part of a component’s API. This enables you to directly call a method in a component’s client-side controller instead of firing and handling a component event.
What is $a in lightning Salesforce?
$A is how you gain access to the underlying Aura framework, such as enqueuing actions, getting application events, managing the Aura rendering life cycle, and various utility methods.
What is Aura value provider?
Value providers are a way to access data. Value providers encapsulate related values together, similar to how an object encapsulates properties and methods. The value providers for a component are v (view) and c (controller).
How do you use a session in lightning component?
Why is lightning a component?
Lightning makes it easier to build responsive applications for any device. Why Use the Lightning Component Framework? The benefits include an out-of-the-box set of components, event-driven architecture, and a framework optimized for performance. Components are the self-contained and reusable units of an app.
What is lightning experience?
Lightning Experience is a modern user interface that helps your sales reps sell faster and your service reps support customers more productively. Lightning Experience includes many new features and entirely redesigned pages, but not every Salesforce feature is supported in Lightning Experience.

What is difference between LC and LWC?
The most notable difference between LWC and LC is the component bundle structure. While you will find similarity between some of the files in the bundle, but there are major differences. LWC component requires a folder to host all component files. The folder sits on the root /lwc folder which hosts all the LWCs.
What is Shadow DOM in LWC?
Shadow DOM is a standard that encapsulates the internal document object model (DOM) structure of a web component. Encapsulating the DOM gives developers the ability to share a component and protect the component from being manipulated by arbitrary HTML, CSS, and JavaScript.
Why LWC is faster than aura?
Faster Sites & Better Performance : LWC is a lightweight framework which is built on web standards and because there is no added abstraction layer, LWC is likely to render faster than aura components since performance is important to deliverability.
What is difference between controller and helper in lightning bundle?
A controller contains functions to handle events in the component. A helper contains utility functions that can be reused in the component bundle; for example, by a controller and a renderer. You don’t have to use a helper but it can be helpful (pardon the pun) for reuse.
