首先必须是密码已过期,你可以使用 passwd command,用于通过指定-e或--expire开关以及用户名来更改用户的密码 # passwd --expire rumenz 接下来验证用户 rumenz 密码过期和老化信息 chage command # chage -l rumenz 运行后 passwd command 上面,你可以从输出中看到 ch
但是JavaScript的abstract是一个保留字,并没有提供抽象类,所以之前我们只是借鉴了工厂方法模式的核心思想。 虽然ES6也没有实现abstract,但是我们可以使用new.target来模拟出抽象类。new.target指向直接被new执行的构造函数,我们对new.target进行判断,如果指向了该类则抛出错误来使得该类成为抽象类。下面我们来改造代码。 c...

Oops. In this example, the component function types don’t line up! For `f`'s input, we wanted type `b`, but what we got was type `M(b)` (a monad of `b`). Because of that misalignment, `composeM()` needs to unwrap the `M(b)` that `g` returns so we can pass it to ...
The main idea is to show how OOP (Object Oriented Programming) concepts can be projected to FP (Functional Programming) while accomplishing the same tasks. It’s always good to base on specifics for the sake of an example. So, I’ve chosen the JavaScript vs. ReScript combo for the illust...
As a concrete example, consider a ‘user manager’ component on the server. In terms of middleware, we’d have both finals and intermediates. For our finals, we’d have such features as creating a user and listing users. But before we can perform those actions, we need our intermediates ...
