A Short Introduction to Lightning Web Components

Sharing is caring!

Salesforce, the global leader in CRM, has introduced a new programming platform called Lightning Web Components (LWC) in December 2018, in comparison to the existing Aura Framework. 

Lightning Web Components are custom HTML elements created using HTML and modern JavaScript that is widely used to build a highly personalized, customizable User Interface(UI) without using JavaScript or creating a Library.

Lightning Web Components and Lightning components can co-exist and work together on a single page. Both of these components appear as Lightning Components for admins and end-users. 

What Are Lightning Components?

Lightning Components can be defined as a user interface (UI) framework that is used to create robust Single Page Applications (SPAs) for desktop and mobile technologies.

Salesforce Admins make use of these components for creating single-page web applications that deliver an end-to-end customer experience on the Salesforce platform to facilitate a variety of functions. Lightning Components can be created, divided, and integrated seamlessly with all the other components that let you create highly customized and sophisticated pages using the flexible page layouts.

What Are Lightning Web Components?

Lightning Web Components are the new and enhanced web standards-based framework method that can be used to create lightning components on the Salesforce Platform. Lightning Web Components utilize standard technologies such as CSS, HTML, and updated JavaScript without the need of a set framework, incorporating the latest innovations in JavaScript like Shadow Document Object Model (DOM), custom elements, and web components.
