Is this value not a JS Boolean? This module works cross-realm/iframe, and despite ES6 @@toStringTag.

I made this just for fun. Don't be mad.

Example

// with jasmine
expect(isNotBoolean(new Boolean(42))).toBeFalsy()
expect(isNotBoolean(false)).toBeFalsy()
expect(isNotBoolean(Object(false))).toBeFalsy()
expect(isNotBoolean(true)).toBeFalsy()
expect(isNotBoolean(Object(true))).toBeFalsy()
 
expect(isNotBoolean(undefined)).toBeTruthy()
expect(isNotBoolean(null)).toBeTruthy()
expect(isNotBoolean('foo')).toBeTruthy()
expect(isNotBoolean(function () {})).toBeTruthy()
expect(isNotBoolean([])).toBeTruthy()
expect(isNotBoolean({})).toBeTruthy()
expect(isNotBoolean(/a/g)).toBeTruthy()
expect(isNotBoolean(new RegExp('a', 'g'))).toBeTruthy()
expect(isNotBoolean(new Date())).toBeTruthy()
expect(isNotBoolean(42)).toBeTruthy()
expect(isNotBoolean(NaN)).toBeTruthy()
expect(isNotBoolean(Infinity)).toBeTruthy()
