JavaScript is a scripting language. Scripting languages:

• interpret and automate a list of tasks that would otherwise be executed one-at-a-time by a person.
  
• interpret and execute a list of tasks once the list is compiled.
  
• need the server to interpret a script and to return the appropriate responses.
  
• perform their functionality on the server side, which reduces processing time dramatically.
