Readme
shouldbe
shouldbe is a type-checking utility for JavaScript code that lives write in your code and throws up if underscore says the value is not of the given type.
Example
shouldbe("string", str) // throws if _.isString(str) would return false
Dependencies
Underscore is the only dependency right now.
How to add more types
Just add the relevant mixin to underscore.
For example:
_.mixin({
isEvenValue: function (val) { return !(val % 2); }
});
shouldbe("even-value", 3); // throws up!
