• assert-kindof: Check native type of the given value and throw TypeError if not okey. Expressive, elegant, behavior-driven API, good descriptive default error messages, simple and clean syntax.
• assertit: Thin sugar layer on top of testit framework, is-kindof and assert.
• is-kindof: Check type of given javascript value. Support promises, generators, streams, and native types. Thin wrapper around kind-of module.
• is-typeof-error: Check that given value is any type of error and instanceof Error
• is-singular: Return true if given word is in singular form like apple, car, test and false otherwise, never throws.
• kind-of-extra: Extends kind-of type check utility with support for promises, generators, streams and errors. Like kindof(Promise.resolve(1)) === 'promise' and etc.
• kind-error: Correct inheriting from Error. Supports constructing from an object of properties - focused on assertion.
• plugin-error: Error handling for vinyl plugins. Just an abstraction of what's in gulp-util with minor changes.
