Let's write Python, Ruby, PHP, Java, JavaScript side respectively

at first

I wrote the code for Python, Ruby, PHP, Java, and JavaScript when I published the performance comparison report for each code in class, so I will omit them and list only the side: smiling_imp: I would be very grateful if you could tell me how to write it incorrectly, or if there is something that should be done individually.

This time, as a sample, a class is created, a fuga method is defined, and fuga is called as an initial process.

JavaScript code: squirrel:

Since there is no class, make it a closure, create a prototype, and call the fuga method from the constructor.

.js

var Hoge = (function(value) {

  //Initial processing
  function Hoge(value) {
    this.hoge = value;
    this.fuga();
  }

  //fuga method
  Hoge.prototype.fuga = function() {
    console.log("fuga");
  };

  return Hoge;
})();

new Hoge(10000000);

Ruby code: gem:

Create a class and call the fuga method from ʻinitialize` as the initial process

class Hoge
  HOGE = "hoge".freeze

  #Initial processing
  def initialize()
    fuga
  end

  #fuga method
  def fuga
    puts "fuga"
  end
end

Hoge.new()

Python code: snake:

Create a class and call the fuga method from __init__ as the initial process

class Hoge(object):
    HOGE = "hoge"

    #Initial processing
    def __init__(self):
        self.fuga()

    #fuga method
    def fuga(self):
        print "fuga"

Hoge()

PHP code: elephant:

Create a class and call the fuga method from __construct as the initial process

.php

<?php

class Hoge
{

    #Initial processing
    public function __construct()
    {
      $this->fuga();
    }

    #fuga method
    private function fuga()
    {
      print "fuga";
    }
}

new Hoge();

Java code: coffee:

Call the fuga method from the main method

public class Hoge {
  private staitc final String HOGE = "hoge";

  //Initial processing
  public static void main(String[] args) {
    new Hoge().fuga();
  }
  
  //fuga method
  public void fuga() {
    System.out.println("fuga");
  }
}

Finally

I compared the four codes. When I wrote class and method and compared them, there was not much difference, but there are some differences for each language.
