• A template processor (also referred to as a
  template engine or template parser) is software
  designed to mix templates with a knowledge model
  to supply result documents.
• The language that the templates are written in is
  understood as a template language or templating
  language.
• In simple words, A template engine is a mechanism
  that enables you to use static template files in
  your application.
• Template engine replaces the variables inside a
  web template file with actual values(at runtime),
  and transforms the template into an HTML file
  sent to the client with the dynamic data. This
  technique makes it easier to style an HTML page.
• From the below diagram the functionality of
  Templating Engines is clear i.e. how the data
  from the database are shown on the HTML page
