Learning scripting languages


Summary


A scripting language is programming language that tells the computer what exactly to do in terms of a specific script or a language. They not only make your work faster, but also can make your job easier! Scripting languages can range from highly domain specific languages to general purpose programming languages. Use of scripting language is not just limited a specific domain, it can be used in any programming environment which requires user to do a repeated manual effort, script automates. How effective is automation is as good as how good is script. As an example a well coded script can make 1 full day manual effort to be completed in 2 minutes of script run. Hence learning scripting languages will be quite useful.
