What’s the Quickest Programming Language?

You may assume there’s a one-word reply to the query: What’s the quickest programming language? However really, there’s quite a lot of technical nuance in the case of velocity and programming. For starters, quicker will not be essentially higher — it actually relies on the use case. (However we’ll get to that.)

Right here, we lay out precisely what makes a programming language “quick,” why it issues, and how one can get began studying a number of the quickest programming languages on the market.

What makes a programming language quick?

The important thing characteristic of a programming language that determines {that a} language is quick is whether or not it’s a compiled or interpreted language. Compiled languages — like Lisp, C++, Go, Rust, and Swift — have to be transformed to machine code (see Meeting beneath) that talks on to the {hardware}. Interpreted languages like Python, JavaScript, Ruby, and PHP run by changing your supply code on the fly into machine code as it’s operating. As a result of this conversion course of occurs whereas the code is operating and provides overhead, interpreted languages are slower than compiled languages.

There are a few different elements that may decide the velocity of a language. Take Java and C# — these languages are each compiled and interpreted. Nevertheless, as a substitute of being compiled to Meeting code, they’re compiled to bytecode. The compiled bytecode is interpreted to run in a digital machine that’s optimized to talk on to the {hardware}. You possibly can consider bytecode as Meeting language for the VM. This makes these languages quicker than a language like JavaScript, which converts text-based supply code instantly into machine code.

One other issue is whether or not it’s a statically-typed language or a dynamically-typed one. Statically typed languages decide the kinds of all variables when the language is compiled, and dynamically typed languages verify the kind of variables whereas the code is operating. This real-time sort checking comes with some overhead, making dynamically typed languages slower than statically typed languages.

What are the quickest programming languages?

The quickest programming language interacts instantly with the machine. Let’s check out a number of the quickest languages you may encounter, and what they’re used for.


Meeting language will not be actually one particular language. It’s simply the title given to any low-level programming language that communicates instantly with a pc’s {hardware}. Because of this Meeting to your laptop computer will likely be completely different from the Meeting to your mobile phone, as a result of they’ve completely different CPUs that require completely different directions. Often, solely builders who work instantly with {hardware} or create programming languages use Meeting.


Lisp is likely one of the earliest programming languages and is now over 60 years outdated. There have been many sorts of this language, and plenty of different programming languages have used a number of the identical options as Lisp. Clojure, for instance, is a contemporary Lisp dialect carried out for the Java Digital Machine, however Clojure will not be why Lisp is on this record. Frequent Lisp compiles on to Meeting language, which signifies that the code you write in Lisp will likely be Meeting when it runs as an executable. Lisp remains to be used as we speak, however you’ll most frequently discover it as Clojure reasonably than Frequent Lisp.


C and C++ are additionally compiled languages. C is a straightforward, procedural programming language that was initially developed within the early Nineteen Seventies and remains to be broadly used as we speak, primarily in embedded functions, due to its velocity and small dimension. C++ is a language that extends C and provides object-oriented options. Due to this, it has changed C in lots of functions. C++ is used in conditions the place efficiency is vital, like 3D online game growth and working system growth.


Go, often known as Golang, is a programming language developed by Google. It compiles to Meeting like many of the different languages right here, but it surely has extra trendy options, easier syntax, and is simpler to write down than the long-time chief of quick programming languages, C/C++. Golang is commonly utilized in community servers and distributed programs the place its velocity can add extra efficiency to those programs.


Rust is one other compiled programming language that can be a safer various to C/C++. It focuses on velocity, reminiscence security, and parallel processing and is commonly utilized in sport engines, browser elements, and VR simulation engines the place velocity is a precedence.


C# is a language, like Java, that first compiles to a digital language after which is interpreted by a VM. This provides it the options of an interpreted language whereas including some velocity. C#, developed by Microsoft, is simple to be taught, and has many third-party libraries that make growth faster and simpler. It’s fashionable for creating desktop functions, video video games, and net companies.


Java compiles to bytecode which is then interpreted by the Java Digital Machine. It was one of many first programming languages to do that, which is why it shortly turned (and stays) fashionable. Utilizing a VM signifies that a Java utility will be moved from one working system to a different with no modifications to the code so long as there’s a model of the JVM for the working system out there. This cross-platform characteristic mixed with its velocity makes Java a well-liked language for a lot of functions, together with net growth, desktop growth, sport growth, cellular app growth, and far more.


Swift is a contemporary programming language developed by Apple that compiles to Meeting code. It was designed to interchange the older Goal-C language. It’s used to develop your favourite Apple merchandise, like Apple TV, the Apple Watch, and iPhones and iPads. Swift is now the preferred language for Mac OS X and iOS growth, however it is usually cross-platform and is beginning to see use in different functions.

It’s not all the time about being quick

Whereas velocity will be vital when contemplating a programming language to make use of, there are many different elements to consider. If you find yourself writing code, there will likely be instances that different options of a programming language are extra vital than being quick. In any case, if velocity had been the highest precedence for each undertaking, programming languages not on this record wouldn’t have a lot use, and we’d be writing Meeting code. Nevertheless, the reality is that a number of the hottest programming languages aren’t even on this record.

Pace is relative, and plenty of instances, a program in C++ will likely be ten instances quicker than a program in Python, but it surely simply doesn’t matter in that particular utility. In any case, if an operation finishes in .001 seconds as a substitute of .01 seconds, can you actually inform the distinction? The distinction, although, will matter if you need to carry out that very same operation 1000’s of instances in a loop.

A variety of the time, velocity of growth issues much more than the velocity of execution. A sluggish program will be scaled to enhance its efficiency by throwing extra assets at it, and computing assets are low cost in comparison with paying for extra growth time to write down code in a low-level language that’s extra advanced to write down. Slower programming languages are fashionable as a result of they’re simpler to write down, have a wealth of third-party libraries out there, and will be deployed faster. All of this hastens growth time.

Be taught extra

Whereas the velocity of a programming language will not be all the time the most vital characteristic, there are particular advantages to being fast. Happily, you can begin studying these as we speak with our self-paced on-line programs. Listed below are some nice locations to begin:

As soon as you become familiar with these coding languages, you’ll be capable of use these in a variety of roles and profession alternatives.
