Does not create. By Priya Pedamkar. Programming language defines a specific set of instructions that can be used to produce various kinds of output.
The programming language description is basically divided into two parts: Syntax and Semantics. Syntax provides a form, whereas Semantics provides meaning to the program. Scripting languages are basically high-level, general-purpose languages that are dynamic in nature. A scripting language is a programming language that does not require an explicit compilation step and support scripts.
Scripting languages are often interpreted rather than compiled. Today, a difference between programming and scripting languages is becoming more and more blurry since compilation can be pretty fast modern hardware and compilation techniques. Scripting or writing scripts is like programming within a program. The traditional approach with scripting is such that one would write scripts to automate certain functionality within another program.
Reason: Compiled programs generally run faster than interpreted programs since compilers read and analyse the code at once and collectively report errors if any. An interpreter, however, reads and analyses a code line by line, and every time it detects an error, it stops addressing them one by one.
Scripting languages are mostly high-level languages that use interpreters to convert the codes written to machine language by executing the codes line by line during runtime. Python is a high-level interpreted programming language referred to as one of the most popular scripting languages. It is standard high-level to middle-level object-oriented programming languages using compilers to compile the codes before execution.
Compilers are programs that convert high-level or middle-level languages into machine language or machine code to allow the computers to read and then execute it. Interpreters analyze the codes line by line and prefer to perform executions of those lines individually. They are slower than compilers but are used by popular programming languages such as Python, JavaScript, and Ruby. PHP is one of the fastest scripting languages, and it is very popular as well. However, ASP is reported to be the fastest scripting language that is currently available.
There are two types of scripting languages: server-side scripting language and client-side scripting language.
