8 ECMAScript standards to learn before building Lightning Web Components

With all the advances in JavaScript and Web standards in the last five years, it’s critical to understand certain concepts and constructs before you begin developing using the LWC programming model.

Salesforce is embracing and supporting the use of Open Source and JavaScript standards for dramatically improving speed and simplicity in LWC development. Salesforce is so serious about these standards, they’ve joined ECMA International, which oversees the ECMAScript variant of JavaScript.

If you are an Apex or Aura developer and want to be prepared for the latest and greatest, this will help you understand important standards that are core to the foundation of LWC. You will learn best practices and be better prepared for LWC development.
