Why doesn't JavaScript ES6 support multi-constructor classes?

Question

I want to write my Javascript class like below.

class Option {
    constructor() {
        this.autoLoad = false;
    }

    constructor(key, value) {
               


        

Answer 1

you can use static methods,look at my answer to same question

class MyClass {
    constructor(a,b,c,d){
        this.a = a
        this.b = b
        this.c = c
        this.d = d
    }
    static BAndCInstance(b,c){
        return new MyClass(null,b,c)
    }
}

//a Instance that has b and c params
MyClass.BAndCInstance(b,c)
