Questions tagged [scripting]
A type of programming, often meant to be easier to learn than more "traditional" programming. Scripting is often used when performance is less important than ease of use. Examples of scripting languages are: Javascript, Lua, Perl, Python, and PHP. Scripting languages are often interpreted instead of compiled, and thus they can be executed directly without generating machine code.
