オブジェクトとクラスをjavaScriptとpythonで比べる

紛らわしいので、記事にして、アウトプットしておく。

クラスandインスタンス化

javaScript

class Person {
    run() {
        console.log("run")
    }
}
const person = new Person();
person.run();

python

class Person(object):
    def run(self):
        print("run")

person = Person()
person.run()

__init__とconstructor

javaScript

class Person {
    constructor(name) {
        this.name = name;
    }
    run() {
        console.log(this.name);
        console.log("run")
    }
}
const person = new Person('Mike');
person.run();

python

class Person(object):
    def __init__(self, name):
        self.name = name
    def run(self):
        print(self.name)
        print("run")

person = Person('Mike')
person.run()

継承

javaScript

class Person {
    constructor(name) {
        this.name = name;
    }
    run() {
        console.log(this.name);
        console.log("run");
    }
}

class newPerson extends Person {
    talk() {
        console.log("talk");
    }
}

const new_person = new newPerson('Mike');
new_person.run();
new_person.talk();

python

class Person(object):
    def __init__(self, name):
        self.name = name
    def run(self):
        print(self.name)
        print("run")

class newPerson(Person):
    def talk(self):
        print("talk")

new_person = newPerson("Mike")
new_person.run()
new_person.talk()

オーバーライド/super()

javaScript

class Person {
    constructor(name) {
        this.name = name;
    }
}

class newPerson extends Person {
    constructor(name, age, gender) {
        super(name);
        this.age = age;
        this.gender = gender
    }

    year() {
        console.log(this.name + this.age)
    }

    sex() {
        console.log(this.gender)
    }
}

const new_person = new newPerson('Mike',"18","man");
new_person.year();
new_person.sex();

python

class Person(object):
    def __init__(self, name):
        self.name = name

class newPerson(Person):
    def __init__(self, name, age, gender):
        super().__init__(name)
        self.age = age
        self.gender = gender

    def year(self):
        print(self.name + self.age)

    def sex(self):
        print(self.gender)

new_person = newPerson("Mike", "18","man")
new_person.year()
new_person.sex()
