Class like behavior

[joegaudet]

In addition to strict enumerations one of the things I love about enums in other languages (Java comes to mind) is having them behave like classes.

I have a small TS library that shows an example of how I like to use them as a pattern in JS/TS applications.

Additionally the truth helpers have been really useful in reducing proliferation of comparisons.

if (order.state.isOpen) {

}

Instead of

if (order.state === OrderState.OPEN) {

}
