Top 10 Fastest Programming Languages in the world!

Let everybody knows

Do you know who interacts with the Computer?

Programming language is the one that interacts with the computer. It’s is a set of instructions for the computer to perform certain tasks which we require. Approximately there are 700 programming languages. Then which among them is the fastest programming language? Do you ever think about it! If not here you can go with the 10 fastest programming languages!

The speed of the programming language depends upon various factors like,

  1. Security
  2. Compiler
  3. Statically typed and dynamically typed
  4. Cross-Platform

Security :

We know that languages like C carry plenty of vulnerabilities. It becomes the compiler’s job to check the vulnerabilities. Till now some popular languages are having major errors.  Let’s see some of the examples Python suffers from input validation, PHP is vulnerable to Cross-site scripting, C suffers from buffer errors. And this is why the compilation process is a bit slow to make source code go through various security checks. And thus fastest language in this list is not best in terms of security but better than others in execution time.

As we know that the compiled languages are going faster than interpreted languages because the interpreter scans the program line by line and converts it into machine code whereas the compiler compiles all the code into machine code at once. So the execution becomes slower when we use interpreters. Here the compiler does smart work while compiling it converts high-level language into intermediary code which saves more time during execution. Even the computer executes intermediary code much faster than interpreters.

Cross platform :

The source code would undergo both compilation and interpretation in some languages like C# and Java. This is cross-platform.  Because of this cross-platform usage and conversion, speed will be compromised which makes these languages slower than other languages.

Let’s counts from 10,

 10. Pascal:


    Pascal was originally developed by Niklaus Wirth in the early 1970s. It’s an Algo-based language and also Algo 60 is a subset of Pascal. Basically, Pascal is a procedural and high-level programming language. It’s open-source software and runs on Mac OS, Windows, Linux. Pascal is a statically typed language and it runs faster than other languages which are not on this list.

9. F#


F# Software Foundation, Microsoft, and open contributors developed F# language. It is an open-source cross-platform programming language. F Sharp is a functional-first, general-purpose strongly typed, multi-paradigm programming language.   It has the speed as same as the speed of C# but the asynchronous code runs faster in C# than in F#. For F# there is no native compiler that’s the for it to hit below C#.

8. C#

   C-sharp is a programming language that runs on the .NET framework and was developed by Microsoft. It is a General-purpose multi-paradigm programming language.  We can create web apps, desktop apps, mobile apps, games, and much more by using the C# language. It’s in our 8th option because it has some limitations like poor cross-platform GUI, the application must be windows based as it is the internal part of .NET, and it is also less flexible when compared with upcoming languages in our list.

7. Java

  Java is a general-purpose programming language and it was developed by James Gosling. Java is platform-independent which makes it run on any platform. Java is excellent in performance and allows us to perform any task at the same time. Java runs on JVM(Java Virtual Machine). The code is first converted into bytecode by the compiler and then it invokes the  Java Interpreter.  Here the classloader loads the byte code into the OS then, the bytecode verifier of java checks the bytecode for security after this the execution engine converts the byte code into machine code. Since this process is too slow when compared to C and C++ it is in our 7th position.

6. Ada


Ada is a  general-purpose, static, high level and objects oriented programming language.  It is more reliable and supports concurrent programming. Although it is fast in performance, it is not strong in security aspects. Programmers often say that programs written in Ada have fewer bugs and are executed faster and also it Ada compilers can find the errors more efficiently. Ada is used worldwide starts from missile control to payroll processing to air traffic control. Reliability is the advantage of Ada but to achieve that it compromises its speed so it is in the position of 6.

5. Julia


    Julia was designed by Jeff Bezanson, Alan Edelman, Stefan. It is a high-level, high-performance dynamic programming language.   We can build applications and microservices. It supports multiple platforms. Julia can also be integrated by other programs. JIT compiler and its design decisions make it run fast. Being a dynamic language it is in the position of no.5 in our list.

4. Fortran


   John Backus developed the Fortran language. It is a general-purpose programming language that is specially designed for numeric computation and scientific computing. It is used for ranking the fastest supercomputers and it is known for its high performance. Being the fastest programming language it is used for numerical programming. Fortran spends a lot of time reading and writing the data, so it is slower than the top 3 languages

3. Rust


Rust is a language that is designed for high-level, multi-paradigm, and for performance safety. It has no runtime or garbage collector so rust is fast. It is inherently safer and becomes slower than C++. Also, the same safety can be obtained from C++ by using pointers but rust is safer by default. While compiling it undergoes various safety checks. At last, we came to know that safer languages are slower by nature.

2. C++


 Most efficient and fastest language C++. As it has its execution speed and standard template libraries it is mostly used by competitive programmers. By errors like buffer error, it suffers from vulnerabilities even though it is more popular.   At more or less the speed of the predecessor, C++ execution takes place. C++ code undergoes security checks by default which makes it slower than C the only reason to make C++ below C in speed so that it is safer and complex than C.

1. C


The special thing in C is it is simple.  And it is also close to assembly language. There are a lot of instructions directly mapped to assembly instructions in C. By compromising security here comes the extreme speed of C. This language is popular among all languages since it has a large number of vulnerabilities.  Without cross-checking, it executes unsafe instructions.  It also suffers from buffer error. Even though it has more disadvantages it tops the list because of its fastest execution speed.
