🔊 In this video we test the speed of programming languages:

• Python
• JavaScript
• Rust
• Shell Script
• Java
• C++
• C
• PHP
• Ruby
• Go

And at the end we created a ranking with Awk.

The video is in Brazilian Portuguese, but you can use subtitles and translate into your language.

Code of Languages

01. SHELL SCRIPT vim sh.sh

for i in {1..1000000};
  do
    echo -en "${i}Ok\r"
done

• Run: sh sh.sh
• Test: time sh sh.sh

02. PHP vim php.php

<?php

for( $i = 0; $i <= 1000000; $i++ ){
  echo "{$i}Ok\r";
}

• Run: php php.php
• Test: time php php.php

03. JAVASCRIPT vim js.js

for( var i = 0; i <= 1000000; i++ ){
  process.stdout.write( i + "Ok\r");
}

• Run: node js.js
• Test: time node js.js

04. RUBY vim ruby.rb

for i in 1..1000000 do
 print "#{i}Ok\r"
end

• Run: ruby ruby.rb
• Test: time ruby ruby.rb

05. PYTHON vim python.py

for i in range(1000001):
    print( str(i) + "Ok\r", end='' )

• Run: python python.py
• Test: time python python.py

06. JAVA vim java.java

class java {
  public static void main ( String args[] ) {
    for ( int i = 0; i <= 1000000 ; i++ ){
      System.out.print( i + "Ok\r" );
    }
  }
}

• Run: javac java.java && java java
• Test: time java java

07. GO vim go.go

package main
import (
  "fmt"
)

func main() {
  for i := 0; i <= 1000000; i++{
    fmt.Printf("%vOK\r", i)
  }

}

• Run: go build go.go && ./go
• Test: time ./go

08. C++ vim cpp.cpp

#include <iostream>

int main(){
  for (int i = 0; i <= 1000000; i++) {
   std::cout << i << "Ok\r";
  }
  return 0;
}

• Run: g++ cpp.cpp && ./a.out
• Test: time ./a.out

09. RUST vim rust.rs

fn main() {
 for i in 0..1000001 {
    print!("{}Ok\r", i);
 }
}

• Run: rustc rust.rs && ./rust
• Test: time ./rust

10. C vim c.c

i#include <stdio.h>

int main(){
  for (int i = 0; i <= 1000000; i++) {
    printf("%iOk\r", i);
  }
  return 0;
}

• Run: gcc c.c && ./a.out
• Test: time ./a.out

Peace!
