#Tillstand

Check, toggle, affirm, and negate states via BEMIT-style classes.

###Usage All methods accept two parameters: element (the elements manipulated) and stateName (name of the state managed). The element parameter must be either a single Element or a NodeList, Array, or jQuery object of Elements; the stateName parameter must be a string. Tillstand works by governing the occurrence of two classes constructed from the stateName parameter — is-{stateName} as affirmative and not-{stateName} as negative.

import tillstand from 'tillstand';

tillstand.check(document.body, 'nefarious');
// returns a boolean given the occurrence of the affirmative class
// so here returns false

tillstand.affirm(document.body, 'nefarious');
// toggles the affirmative class
// so here gives body the class 'is-nefarious'

tillstand.negate(document.body, 'nefarious');
// toggles the negative class
// so here removes 'is-nefarious'
// and adds in 'not-nefarious'

tillstand.toggle(document.body, 'nefarious');
// toggles between the affirmative and negative classes
// so here replaces 'not-nefarious' with 'is-nefarious'
