Salesforce Lightning Web Components – An Introduction

Salesforce Lightning Web Components has been doing great with the Lightning modules. Salesforce launched the Lightning component framework approved by the Aura programming framework.

Earlier, the web standards provided inadequate feasibility and were incapable to develop large-scale web applications.

These ongoing technology innovations in operating systems, programming languages, web servers, and database software have experienced an exceptional level of standardization.

This innovation changed a basic page-rendering platform into an adequate web development platform and now it is commonly recognized as Lightning Web Components.

Lightning web components are custom HTML elements built using HTML and modern JavaScript. These web components provide simply what’s important to work well in browsers supported by Salesforce, they use core web components standards.

Salesforce Lightning Web Components are lightweight and provide excellent performance as they are built on code (written in JavaScript and HTML) that works natively in browsers.

What are Salesforce Lightning Web Components?

Salesforce lightning web components are committed to developing open web standards.

Lightning Web Components are defined as an updated web standards-based framework method for developing lightning components on the Salesforce Platform.

These web components use standard technology like HTML, CSS, and updated JavaScript without any need for a set framework, including the most advanced innovations in JavaScript, incorporating custom elements, shadow document object model (DOM), and other web components.

Lightning web components are simpler to set and expand as they are in line with updated web standards.
