I will accept any syntax that can pass muster (the weird hybrid between
colon and C style I came up with is never getting in :P) btw, I do think
having generics/template syntax is useful (at one point I was planning on
implementing templates in my transpiler, which is why I support the
syntax).

I like that syntax.
I wonder about the runtime semantics of it, though. (I know TypeHint
is a TODO, but…)
Is there any implication at runtime of a function that returns a String?
Is this:
```js
var point = {
x Number,
y Number
};
```
… the same as this?
```js
var point = {
x: Number(),
quick personal thoughts on this matter, leaving the named arguments part
beside (as it is looks kinda redundant/unnecessary effort that could wait)
We've been talking about types for long time in here and the good old
direction was *binary data* in the form of `StructType`

Syntax for putting properties on the prototype was long-ago rejected
because of footgun potential.
Correction: *data* properties. : )

TypeScript was just an example, but being class a different Syntax beast
than just prototype (right?) why would that be bad? It will be indeed
not-unexpected as Kevin mentioned later on.
Using classes thinking prototypes feel something developers won't do
(specially new comers) so TypeScript
Why can't we use proxy or a new global object call StrictType, or a new
property call definePropertiesType on the global Object
Than we could use the syntax style of the language :
Object.definePropertiesType(object,{
age:{type:Number},
name:{type:String},
height:{type:Float}
});

Mark, properties on the prototype are in TypeScript, and probably every
other OOP based language. Defaults can be easily defined as such, i.e.
```js
class Person { name = 'anonymous'; age = 0; }
```
Not only, defaults could be optimized upfront by parsers without needing to
infer or do extra

Anyway, I'm curious to know why do you think getters and setters are OK
and properties are not. I don't see any technical difference, specially
considering get/set for lazy property computation/assignment through the
prototype getter anyway.
Syntax for putting properties on the prototype
Also static properties are on __proto__, so it seems a bit strange that
instance properties would not also be on .prototype. Somewhat of a
consistency issue I suppose.
Methods declared as static in ES6 are defined on the constructor itself.
Apparently, static data properties in TS are

Hello All,
I wanted to share some ideas with you for type hinting:
https://github.com/lukescott/es-type-hinting
I’m also putting this together for named parameters:
https://github.com/lukescott/es-named-arguments
The two are somewhat related. The type hinting doc uses white-space instead of
21 matches
