LWC Simplified: A Beginner’s Guide to Salesforce Coding

If you are new to coding on Salesforce, the acronyms can be confusing. Aura? Visualforce? Apex? Forget the history for a moment—the future is Lightning Web Components (LWC). Simply put, LWC is the modern, easy way to build custom buttons, forms, and apps inside Salesforce.

What is LWC?

Think of LWC as standard web development. If you know a little HTML (the structure) and JavaScript (the logic), you are already 90% of the way there. It uses standard browser tools, which makes it much faster and easier to learn than older Salesforce frameworks.

The 3 Building Blocks

Every component you build is just a bundle of three files that work together:

• HTML: This is what the user sees (the buttons, text, and inputs).

• JavaScript (JS): This is the brain. It handles the clicks and the data.

• XML: This is the configuration. It tells Salesforce where your component can be dropped (like on a Home Page or a Record Page).

"You don't need to be a wizard to write LWC. It’s just modern web standards, living inside Salesforce."

What Makes LWC Different?

Unlike legacy frameworks that require heavy abstraction layers, LWC uses core Web Components standards. This means that if you know standard JavaScript (ES6+), HTML, and CSS, you already know how to build on Salesforce.
