Scripts are often used on websites. Most often they are written in PHP and JavaScript. The first is used to write the part of the site that is not visible to the visitor, that is, the backend, and the second in most cases is responsible for the visual, that is various animations, smooth transitions and other actions (frontend).
If everything is clear with the visual scripts, then the scripts that are invisible to the visitor’s eye collect information in the database, check the correctness of filling out forms and perform other complex tasks.
Accordingly, in the operating system, scripts also perform serious operations. Scripts running through the console (command line) can affect the opening of services and applications, make changes to system files or even install other programs (this is how viruses get into the system).
As for Windows, you can find a built-in CMD (PowerShell) tool which is designed to run scripts stored in BAT format.
Languages that support scripting are used in all fields and for all tasks:
- iOS or OS X development – Swift.
- Android development – Java or Kotlin.
- Game development – C# or C++.
- Web development – PHP, Python, JavaScript.
- Analytics – Python, Java, JavaScript.
- Device programming – Python, C++.
There are no formal restrictions on the use of any particular language in different areas – there just may be some difficulties. For example, you can create an application for OS X even in Python, it will just work slowly. You can create a website interface even in assembly language – but then you will be slow.
As for scripting languages, they are used in special cases, such as:
- WitcherScript or Lua to write a quest for the game.
- VBA for creating a macro for an accounting spreadsheet.
- Also do not forget about scripts – they can also be written by anyone and for anything. For example, to improve the position of the site in search engines.
Scripts provide the functionality of the site. They establish algorithms for behavior in every situation envisioned.
With the help of scripts:
- They collect statistics. This is the number of visits or user behavior on the site.
- There is a communication between the database and the interface of the site.
- Load information on the pages without updating. This is how the button “Show more” works on online shopping sites.
- It is possible to expand the functionality of the resource, add new tools.
- Automate most of the operations required for the SEO-promotion of the site. This frees up time for the webmaster to solve other tasks.
- Add dynamic elements of the design. For example, at the time of the New Year holidays write a script with snowfall animation.
