Do I need to use 'new' operator when creating instance of Immutable.Record?

example from docs https://facebook.github.io/immutable-js/docs/#/Record

var ABRecord = Record({a:1, b:2})
var myRecord = new ABRecord({b:3})

can I omit new operator? it seems to work without it as well..

At least in the current version, you can omit it. If you look into the source code on GitHub, there is a check that makes sure this is correctly bound if you are omitting new.

It is unsafe to omit it, you might encounter problems in future versions. You can easily test whether a given version of Immutable.js supports this feature, like this:

typeof (Record({})) === "function"
