fromSync(input)

• input <string> | <ArrayBuffer> | <ArrayBufferView> | <Iterable> | <Object> 不能是 null 或 undefined。
• 返回：Iterable

from() 的同步版本。返回一个同步可迭代对象。不能接受异步可迭代对象或 Promise。实现 Symbol.for('Stream.toStreamable') 的对象会通过该协议转换（优先于 Symbol.iterator）。toAsyncStreamable 协议将被完全忽略。

🌐 Synchronous version of from(). Returns a sync iterable. Cannot accept async iterables or promises. Objects implementing Symbol.for('Stream.toStreamable') are converted via that protocol (takes precedence over Symbol.iterator). The toAsyncStreamable protocol is ignored entirely.

import { fromSync, textSync } from 'node:stream/iter';

console.log(textSync(fromSync('hello'))); // 'hello'const { fromSync, textSync } = require('node:stream/iter');

console.log(textSync(fromSync('hello'))); // 'hello'拷贝
