英文:
Pure vs Impure methods ES6 classes. Should I pass the values around or should I store them in the object
问题
以下是翻译好的内容：
我对这个主题之前进行过讨论，但我没能在Google上进行适当的搜索，所以我就在这里。
通常在编写类时，我会有一些特定的方法来执行某些操作，在方法内部我会按照以下方式组织每个步骤：
类 MyClass {
......
主方法() {
this.运行验证();
const val1 = this.方法1();
const val2 = this.方法2();
const val3 = this.方法3(val1, val2);
const val4 = this.方法4(val1, val3);
......
返回 最终结果
}
}
我选择仅在当前对象中存储一些特定的值。也许这样更好，或者我在更多的地方使用它并且更容易访问，这取决于情况。
我的问题是哪种做法更好。是我刚才展示给你的那种，还是像下面这段代码中的那种：
类 MyClass {
......
主方法() {
this.运行验证();
this.方法1()
this.方法2()
this.方法3()
......
返回 this.最终结果
}
}
在这种情况下，我是否应该不断地更改当前对象的属性？
英文:
I am 100% sure this topic was discussed before but I didn't manage to give a proper search on google so here I am.
Usually when I am writing classes I have a specific methods which does something and inside it I structure each step like this:
Class MyClass {
......
mainMethod() {
this.runValidation();
const val1 = this.method1();
const val2 = this.method2();
const val3 = this.method3(val1, val2);
const val4 = this.methid4(val1, val3);
......
return finalResult
}
}
and I chose to store in the current object only some specific values. Maybe it is better this way, or maybe I am using it in more places and it is easier to access, it depends.
My question is what would be a better practice. The one I just showed you above, or the one like in the following piece of code:
Class MyClass {
......
mainMethod() {
this.runValidation();
this.method1()
this.method2()
this.method3()
......
return this.finalResult
}
}
where I am constantly changing the properties of the current object?
