What is the NavigationMixin found in NavigationMixin(LightningElement)? Where is it defined? How can I write my own mixins?

Mix-ins are a fairly well-documented feature of many programming languages, including modern JavaScript/ES6. They are used to allow classes to inherit functionality from multiple other classes.

NavigationMixin is a class defined in the lightning namespace. It is documented here and here.

  • Thank you. I know what mixins are, but I had never seen the Mixin(Base) syntax. I thought it was something proprietary to SF/LWC. Now, I understand it's plain old JavaScript (although not well known, at least not to me).
