  3. Programming languages run faster than scripting languages hence they are preferred more over the period to get the best outcomes.
  4. Programming language is code-intensive because most of the functions involve manual handling of the platform whereas scripting involves more codes and less writing work.
  5. Scripting helps to creates standalone apps whereas programming languages enable the creation of apps as a fraction of a hoard.
