Feature reveal for my JS library (HotTea); Typed objects.

#javascript #watercooler #hottea #webdev

I'm adding typed objects to JS in HotTea (along with the promised "real classes").

This is how they look so far:

je = TypedObject({
  "name": String,
  "age": Number
});

je.name // null
je.age // null


je.name = null; // That's fine.
je.name = new Object(); // TypeError: Type Object does not match required type String.
je.name = "John"; // TypeError: Type String does not match required type String.
// Gonna fix the message to account for primitive type names.


je.name = new String("John Egbert");
je.age = new Number(13);

je.name; // John Egbert

There also is a way to use primitive types as their Object equivalents (using the strict parameter):

ds = TypedObject({
  "creator": Object,
  "name": String
}, false);

ds.creator = "test"; // Throws an error (because I still need to implement the proper behavior).
ds.creator = new String("Andrew Hussie");
ds.name = "Dave Strider";

I also do wanna be able to add a way to add new properties later on, but that's gonna be hard due to the current architecture. But, I hope you all are excited for HotTea!
