class CookieHelper {

    getAsObject(cookieObject={}) {
        document.cookie.split('; ').forEach(item => {
            cookieObject[item.split('=')[0]] = item.split('=')[1]
        })
        return cookieObject
    }

    hasKey(key) {
        const cookieObject = this.getAsObject()
        return Object.keys(cookieObject).includes(key)
    }

    addObject(object) {
        Object.keys(object).forEach(key => {
            document.cookie = `${key}=${object[key]};`
        })
    }

    getObjectByKey(key, returnObject={}) {
        returnObject[key] = this.getValueByKey(key)
        return returnObject
    }

    getValueByKey(key) {
        const cookieObject = this.getAsObject()
        return cookieObject[key]
    }

    deleteByKey(key) {
        document.cookie = key + '=; expires=Thu, 01 Jan 1970 00:00:01 GMT;'
    }
    
    flush() {
        for (const key of Object.keys(this.getAsObject())) {
            this.deleteByKey(key)
        }
        
        return this.getAsObject()
    }
}

I will be updating the methods for v2.0, something along the lines of:

.getAsObject() => .get( cookie=null ) - unifies the two methods and uses cookie as an optional parameter, defaulting to all cookies.
.hasKey( key ) => .has( cookie ) - removes implied word "key".
.addObject() => .add( cookie, value ) - removes implied word "key".
.getValueByKey( key ) => .getValue( cookie ) - removes implied word "key".
.flush( keys=[ e, <...> ] ) => .flush( cookie=null )

I will be DEPRECATING the following methods in v2.0, and subsequently REMOVING them in a future release:

.getObjectByKey() => DEPRECATED in favor of .get( cookie=null ).
.deleteByKey() => DEPRECATED in favor of .flush( cookie=null ).
