三种编码方式

一个开灯设置颜色的示例，使用三种编码方式来实现。分别是：脚本化编程、具有函数思维的过程化编程以及面向对象编程。

脚本化编程：

class Light {
    status: string
    color: string
}

function main() {
    const light = new Light()
    if (light.status === "on") {
        throw new Error("The light is on")
    }
    light.status = "on"
    light.color = "red"
}

具有函数思维的过程化编程：

class Light {
    status: string
    color: string
}

function open(light: Light) {
    if (light.status === "on") {
        throw new Error("The light is on")
    }
    light.status = "on"
}

function setColor(light: Light, color: string) {
    if (light.status !== "on") {
        throw new Error("The light is not on")
    }
    light.color = color
}

function main() {
    const light = new Light()
    open(light)
    setColor(light, "red")
}

面向对象编程：

class Light {
    #status: string
    #color: string

    public on() {
        if (this.#status === "on") {
            throw new Error("The light is on")
        }
        this.#status = "on"
    }

    public set color(color: string) {
        if (this.#status !== "on") {
            throw new Error("The light is not on")
        }
        this.#color = color
    }
}

function main() {
    const light = new Light()
    light.on()
    light.color = "red"
}

都是 Light 咋有那么多实现，你慢慢品...，你平常用那一种方式呢？
