What’s the Quickest Programming Language?

You would possibly suppose there’s a one-word reply to the query: What’s the quickest programming language? However truly, there’s numerous technical nuance in the case of velocity and programming. For starters, sooner shouldn’t be essentially higher — it actually depends upon 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 among 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 — should 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 working. As a result of this conversion course of occurs whereas the code is working 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 an alternative 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 sooner than a language like JavaScript, which converts text-based supply code straight 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 examine the kind of variables whereas the code is working. This real-time kind 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 straight with the machine. Let’s check out among the quickest languages you would possibly encounter, and what they’re used for.


Meeting language shouldn’t be actually one particular language. It’s simply the identify given to any low-level programming language that communicates straight with a pc’s {hardware}. Which means that Meeting in your laptop computer will likely be totally different from the Meeting in your mobile phone, as a result of they’ve totally different CPUs that require totally different directions. Often, solely builders who work straight with {hardware} or create programming languages use Meeting.


Lisp is among the earliest programming languages and is now over 60 years previous. There have been many sorts of this language, and lots of different programming languages have used among the identical options as Lisp. Clojure, for instance, is a contemporary Lisp dialect applied for the Java Digital Machine, however Clojure shouldn’t be why Lisp is on this listing. Widespread Lisp compiles on to Meeting language, which implies that the code you write in Lisp will likely be Meeting when it runs as an executable. Lisp continues to be used immediately, however you’ll most frequently discover it as Clojure slightly than Widespread Lisp.


C and C++ are additionally compiled languages. C is a straightforward, procedural programming language that was initially developed within the early Seventies and continues to be extensively used immediately, primarily in embedded functions, due to its velocity and small measurement. 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, also called Golang, is a programming language developed by Google. It compiles to Meeting like a lot of the different languages right here, but it surely has extra trendy options, easier syntax, and is simpler to jot down than the long-time chief of quick programming languages, C/C++. Golang is commonly utilized in community servers and distributed methods the place its velocity can add extra efficiency to those methods.


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 offers it the options of an interpreted language whereas including some velocity. C#, developed by Microsoft, is straightforward to study, and has many third-party libraries that make growth faster and simpler. It’s in style 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) in style. Utilizing a VM implies 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 accessible. 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, cell app growth, and far more.


Swift is a contemporary programming language developed by Apple that compiles to Meeting code. It was designed to exchange 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 additionally it is cross-platform and is beginning to see use in different functions.

It’s not at all times 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 occasions that different options of a programming language are extra vital than being quick. In any case, if velocity have been the highest precedence for each mission, programming languages not on this listing wouldn’t have a lot use, and we’d be writing Meeting code. Nevertheless, the reality is that among the hottest programming languages aren’t even on this listing.

Velocity is relative, and lots of occasions, a program in C++ will likely be ten occasions sooner 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 an alternative of .01 seconds, can you actually inform the distinction? The distinction, although, will matter if you must carry out that very same operation 1000’s of occasions 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 sources at it, and computing sources are low cost in comparison with paying for extra growth time to jot down code in a low-level language that’s extra advanced to jot down. Slower programming languages are in style as a result of they’re simpler to jot down, have a wealth of third-party libraries accessible, and will be deployed faster. All of this hurries up growth time.

Be taught extra

Whereas the velocity of a programming language shouldn’t be at all times the most vital characteristic, there are particular advantages to being fast. Luckily, you can begin studying these immediately 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 to use these in a variety of roles and profession alternatives.
