UPDATE

Maybe hold off on this. Or put browser-based checks in separate export

How do we implement not as function isNot?

Maybe as argument to specific type check?

typecheck(x).isArray(false).yields();

false would indicate that we are checking if the input is NOT an Array, etc

Symbol,
Proxy,
Promise,
Response,

Object matching??

Set,
Map,
WeakMap,

Create an api for adding to checks

We should allow yields to accept a function as an argument. If the check returns false the argument will fire with with the checked input as the first argument.

function logging(input){
  // ....
}
typecheck(x).isArray().yields(logging);

This would additionally allow for new syntax such as:

typecheck(x).isArray().yields(myFunctionTohandleX);

We could also allow a second argument to yields for the handling of a check that returns true:

function trueHandler(input){
  // handle correct input
}
typecheck(x),isArray().yields(falseHandler, trueHandler);

typecheck(x),isArray().yields(null, trueHandler);

Edit!

Probably more intuitive to be the other way around trueHandler then falseHandler
