Dynamic Apex: Get Field Type

Dynamic Apex allows users to access the metadata information about sObject and fields.
The requirement was to get the field type of a sObject.

Schema.DescribeFieldResult f = Schema.sObjectType.Account.fields.Name;

system.debug('## Field Type: '+f.getSObjectField().getDescribe().getType());
//Returns: ## Field Type: STRING
