readable.drop(limit[, options])
稳定性: 1 - 实验
limit
<number> 从可读文件中删除的块数。options
<Object>signal
<AbortSignal> 如果信号被中止,则允许销毁流。
- 返回: <Readable> 丢弃了
limit
个块的流。
此方法返回新的流,其前 limit
个块被丢弃。
import { Readable } from 'node:stream';
await Readable.from([1, 2, 3, 4]).drop(2).toArray(); // [3, 4]
Stability: 1 - Experimental
limit
<number> the number of chunks to drop from the readable.options
<Object>signal
<AbortSignal> allows destroying the stream if the signal is aborted.
- Returns: <Readable> a stream with
limit
chunks dropped.
This method returns a new stream with the first limit
chunks dropped.
import { Readable } from 'node:stream';
await Readable.from([1, 2, 3, 4]).drop(2).toArray(); // [3, 4]
