What does e.force:createRecord in var createContact = $A.get("e.force:createRecord"); do in Lightning Component in Salesforce?

Hii Deepak,

$A.get(“e.force:createRecord”) globally create contact field   and display the record create page for an object, set the object name on the entityApiName attribute and fire the event. recordTypeId is optional and, if provided, specifies the record type for the created object. defaultFieldValues is optional and, if provided, specifies values to use to prepopulate the create record form.
