What is the Lightning Web Component (LWC)?
The Lightning web component introduced in Feb 2019 is Salesforce’s new programming model built on modern browser improvements or web standards.
These web components help to create custom, reusable HTML tags for web pages & apps.
The lightning component uses different components – The lightning web component & the Aura Component.
Most important!
Lightning web component co-exists with the Aura programming model & delivers unparalleled performance.
It is highly useful for:
Improving productivity: Uses modern web language like templates, shadow DOM, Decorators, and custom elements.
Enhanced Performance: Web browser executes the code for a superfast experience.
As per the development in the last five years, there is a complete transformation in the web stack.
From 2014 to 2019, the superfast rise in standard web elements is phenomenal.
Salesforce Lightning web components are like icing on the cake. Now, work is handled efficiently by the web browser.
Lightning web components leverage templates, custom elements, Decorators, Modules, Rendering & events available in ECMAScript 7 & beyond.
Advantages of Lightning web component :
- Offers enhanced security
- Superfast & Light in weight
- Supports advanced browsers technologies like CSS3, HTML5
Aura Lightning Component:
Aura is a user interface framework that develops single-page applications on the Salesforce platform.
It develops reusable component units in the form of a plug & play component. Every aura component performs small tasks independently.
Many aura components work together to create a single application.

Aura Component Programming model offers excellent benefits like:
Out-of-the-box components:
Aura out-of-the-box components ensure that the app does not need optimization for different devices.
Fast Development:
Teams work faster with, out of an box component that functions hassle-free with different devices like mobile & desktop.
Browser compatibility:
Apps are compatible with the latest browser technologies like HTML5.
Benefits of Lightning Web component (LWC) over Aura Lightning Component (ALC)
Site Loading Speed:
LWC (Lightning Web Components) uses a modern framework built on native browser features, allowing faster DOM rendering and efficient resource loading. This results in quicker page load times compared to Aura Components, which rely on a more extensive framework that adds overhead.
Easy Learning:
LWC leverages standard web technologies such as HTML, JavaScript, and modern ECMAScript features, making it accessible to developers familiar with these languages. In contrast, Aura Components require learning proprietary syntax and paradigms, adding to the learning curve.
Best Performance
LWC’s architecture is designed around the core Web Components standards, making it lightweight and efficient. The virtual DOM in LWC minimizes re-renders and enhances memory management, leading to superior performance over Aura Components, which use a more resource-intensive framework.
Debugging Made Easy
Debugging in LWC benefits from the use of standard browser developer tools, making it straightforward to identify and resolve issues. Additionally, a wealth of resources and community support for LWC simplifies troubleshooting, whereas Aura Components debugging can be more complex due to its unique structure.
Easy to Ramp
Since LWC is built on the principles of modern web standards, developers can quickly adapt without needing to learn a new framework. Aura Components, on the other hand, require an understanding of its specific framework, which can slow down the onboarding process.
Standardized
LWC’s reliance on standardized web technologies like CSS, JavaScript, and HTML ensures compatibility and performance across different browsers. This standardization promotes best practices and makes development more predictable compared to the proprietary nature of Aura Components.
Inbuilt Browser Security Features:
LWC has inbuilt browser security features driving its out-of-the-box usage while Aura requires an event-driven programming model that is GUI-dependent. It focuses on actions like button press & clicks determining the flow of movement. The Lightning web components support these actions.
Data Binding:
Data binding is a technique that binds data sources from the provider and consumer together and synchronizes them. LWC supports two-way data binding that helps in coordinating how data moves between different components.
Unit Testing Support:
LWC includes support for standard JavaScript unit testing frameworks like Jest. This integration allows developers to write and run tests efficiently, ensuring code reliability and facilitating continuous integration practices. Aura Components have more limited testing support, making it harder to maintain robust codebases.
Versatility:
LWC’s full encapsulation through Shadow DOM provides isolation of component styles and scripts, preventing conflicts and promoting modular design. This encapsulation makes LWC components more versatile and reusable across different parts of an application compared to the less isolated Aura Components.
