角度分割列表 [英] Angular split list

问题描述

我有一个看起来像这样的列表

I have a list looking like so

[[{A},{B}], {C}]

是否有任何简单的方法，而无需创建一个将其展平为如下所示的数组的函数

Is there any simple method without having to create a function that will flatten this to an array looking like so

[{A},{B},{C}]

我搜索了SO，但是使用打字稿方法却找不到任何东西.

I searched on SO but did not find anything with typescript methods.

谢谢.

A，B和C是相同的类型.

Edit : A, B and C are the same types.

推荐答案

您似乎正在寻找内置的

It appears that what you're looking for is the built-in Array.prototype.flat:

const input = [['foo', 'bar'], 'baz'];
const output = input.flat(); // ['foo', 'bar', 'baz']

请注意，您必须在esnext支持下进行编译.有关更多详细信息，请参见此问题.它也不会在IE或Edge上开箱即用.如果您的用例存在问题，则需要使用上方MDN链接中显示的polyfill.

Note that you'll have to compile this with esnext support. See this question for more details. It also won't work out of the box on IE or Edge. If that's a problem in your use case, you'll want to use the polyfill that's shown in the MDN link above.

替代方法存在于众多库中，例如， lodash ， Ramda 都具有等效的flatten方法.

Alternatives exist in numerous libaries, for example, lodash, underscore.js, and Ramda all have an equivalent flatten method.
