Check
A package for dynamically checking that data matches the criteria you expect it to.
Predicate
In Check a predicate is a pure function that takes in a value and returns true or false depending on whether or not the value passed the predicate's test.
For Example
const isGreaterThan5Pred = x => typeof x === "number" && x > 5;Check
A Check, takes in a single value, tests it against one or more predicates and returns the value if all predicates return true or throws a CheckError if any return false.
