readable.take(limit[, options])
稳定性: 1 - 实验
limit
<number> 从可读块中获取的块数。options
<Object>signal
<AbortSignal> 如果信号被中止,则允许销毁流。
- 返回: <Readable> 带有
limit
个块的流。
此方法返回带有前 limit
个块的新流。
import { Readable } from 'node:stream';
await Readable.from([1, 2, 3, 4]).take(2).toArray(); // [1, 2]
Stability: 1 - Experimental
limit
<number> the number of chunks to take from the readable.options
<Object>signal
<AbortSignal> allows destroying the stream if the signal is aborted.
- Returns: <Readable> a stream with
limit
chunks taken.
This method returns a new stream with the first limit
chunks.
import { Readable } from 'node:stream';
await Readable.from([1, 2, 3, 4]).take(2).toArray(); // [1, 2]
