Today, almost all code is written in one of many programming languages, which have their own libraries, documentation and syntax. Put simply, coding is the act of inputting commands into a computer in a language that it can understand. At the smallest level, computers process everything in binary — 1s and 0s — also called machine code. According to Naukri, computer science graduates can expect to earn as much as 27 per cent more than graduates with non-computer engineering courses [2]. Your level of education, experience, job type, and the scripting language you’re proficient in will influence your salary. These are some of the advantages and disadvantages of scripting languages, but it’s important to note that these limitations can be mitigated by following best practices and using the right tools for the job.
The power of scripting languages is their ability to automate digital tasks. A few lines of code without branching is probably considered a script. A codebase of multiple files, that performs sophisticated user or hardware interface or complicated algorithms or multiprogramming is probably not considered a script.

Although coding and scripting are definitely related terms that people frequently confuse with one another, they’re not the same thing. Featured or trusted partner programs and all school search, finder, or match results are for schools that compensate us. This compensation does not influence our school rankings, resource guides, or other editorially-independent information published on this site. For example, Java is not script-like since an application starts at the function named main which need not be at the top of the code.
- Although coding and scripting are definitely related terms that people frequently confuse with one another, they’re not the same thing.
- For example, when you open a new browser window to perform a Google search or navigate to a specific website, you interact directly with the program that powers the browser.
- While all scripting languages are programming languages, not all programming languages are scripting languages.
- Server-side scripting languages — such as PHP, Ruby and Python — are processed on the host server.
- The use of scripting languages does not require the same time commitment of more complex programming languages.
Meanwhile, process automation at the application level can be done by using VBA and AppleScript. As with scripts in general, scripting languages are mostly used to automate processes at the application level. Ruby is a server-side scripting language used for creating web browsers, but it can be used for other program applications as well. Ruby is open-source, meaning that its original source code is free and available for anyone to use. With the advent of graphical user interfaces, a specialized kind of scripting language emerged for controlling a computer.
Scripting language
Additionally, most scripting language interpreters are slower than compilers. That is because traditional programming languages are usually converted to machine code before being compiled, thus offering faster execution for the users. The term scripting language is sometimes used in a wider sense, to refer to dynamic high-level programming languages in general. Some are strictly interpreted languages, while others use a form of compilation.
This script defines a variable called message and assigns it the value of “Hello World!”. The script is saved with a .js file extension and can be run in a web browser or with a JavaScript runtime environment. At the command line or through a web server, they are able to execute programs running on a web server and display the appropriate uses of a script results to the users. Perl is a general scripting language that’s been around a very long time — since December of 1987, to be exact. Ruby is a strictly object-oriented scripting language, so everything becomes an object when working with it. This is even the case for factors like integers or Booleans which are usually more primitive.
Client-Side Scripting Languages
A server-side scripting language operates on the server to generate responses for client requests, with the primary objective of creating dynamic content for web pages. This approach is considered more secure than client-side scripting, as the server handles the execution, enhancing overall security measures. Examples of server-side scripting languages include PHP, Java, Ruby, Python, C#, and Go. C++ is a general-purpose programming language typically compiled before executing the code. C++ is an object-oriented language that is capable of low-level memory manipulation. It was originally intended for system programming and embedded software in large systems.
Strongly typed variables also mean that they cannot be inadvertently changed to the wrong type. As the figure shows, conventional programming languages take different approaches to preparing the code. If the language is a conventional one such as C or C++, the code is first passed to the compiler for the initial transformation.
Interpreted
Computer programmers, software developers, as well as front-end and back-end developers, use scripting skills in their careers. When looking at scripting vs. programming languages, the difference is that programming languages tell a computer what to do. Many scripting languages, like Python or JavaScript, can also be used to program or build full applications. Many of these languages’ interpreters double as command-line interpreters such as the Unix shell or the MS-DOS COMMAND.COM. Others, such as AppleScript offer the use of English-like commands to build scripts.
Some other types of applications that need faster feature addition or tweak-and-run cycles (e.g. game engines) also use an embedded language. The scripting languages used for this purpose range from the more common and more famous Lua and Python to lesser-known ones such as AngelScript and Squirrel. Far back in computer science history, there was no other way in which users could write code, but quickly programming languages were written to give programmers a far more user-friendly coding experience. Scripting languages are often compared with programming languages as though they’re opposite sides of the same coin. However, scripting languages are actually a subset of programming languages. More often than not, such comparisons are meant to distinguish scripting languages from conventional programming languages.

He can also be found co-hosting the ITPro Podcast with Jane McCallion, swapping a keyboard for a microphone to discuss the latest learnings with thought leaders from across the tech sector. Very recently, AI models have reached a point where they are beginning to be able to overtake humans in writing programs of their own, but this is still far from proven technology.
These are just a few examples of scripting languages that power the web and plenty of applications you and millions of other Internet users execute every day. Based on where the script execution takes place, there are two types of scripting languages such as client side and server side. If you’re wondering, “what is scripting language?” we’ll explain it below. We’ll also highlight the differences in the worlds of scripting vs. programming. Finally, we’ll guide you through the most popular scripting languages and how you can learn and use them. For example, Autodesk Maya 3D authoring tools embed the Maya Embedded Language, or Blender which uses Python to fill this role.
