在 Typescript 中使用 Generics 和 Arrays

[英]Using Generics in Typescript with Arrays

In Typescript, if I'm defining a type that stipulates only strings can go into an array, I'm able to define that like this:在 Typescript 中,如果我定义的类型规定只有字符串可以将 go 放入数组中,我可以这样定义:

type stringArray = string[]

I'm able to specify that certain kinds of objects may go into an array like this:我可以指定某些类型的对象可能 go 进入这样的数组:

type myObject  = { 
    one: string,
    two: string,
}
type objectArray = myObject[]

However, I'm able to accomplish something very similar with generics, like this:但是,我能够完成与 generics 非常相似的事情,如下所示:

type stringArray = Array<string>

and

type objectArray = Array<myObject>

Is there any advantage to using either approach?使用这两种方法有什么好处吗? When should one use the former and when is the latter a better approach?什么时候应该使用前者,什么时候使用后者更好?

Array<T> and T[] are 100% equivalent. Array<T>T[] 100% 等效。

Which to use is mostly a code style choice.使用哪个主要是代码风格的选择。 Though the T[] syntax is usually preferred in most codebases that I've seen as it looks like an array, and at a glance it is shorter.尽管在我见过的大多数代码库中通常首选T[]语法,因为它看起来像一个数组,而且乍一看它更短。
