LWC is not only built on top of the ECMAScript standard, it also provides some nifty syntactic sugar that can transpile into standard JavaScript. Because of this, the LWC framework is able to incorporate proposed language features, which simplifies app development by future proofing your code in the always evolving JavaScript ecosystem. In this post, we'll take a closer look at two relatively recent features—mixins and decorators—and see how they can be used in your LWC apps.
If you'd like to take a closer look at Lightning Web Components, Salesforce has a boilerplate app that's built in TypeScript. There's also a Trailhead lesson to help you learn about web components in less than an hour. Or, feel free to check out the LWC dev docs for more specific reference information.
The evolving nature of these three technologies has lead to the introduction of web components, a cross-browser solution for building complex web apps. On top of this open source standard, Salesforce developed Lightning Web Components (LWC) as a fast, enterprise-grade wrapper around vanilla web components.
