Socket researchers uncover a malicious npm package posing as a tool for detecting vulnerabilities in Etherium smart contracts.
Filter over async iterables.
This method creates a new async iterable with all elements that pass the test implemented by the provided function.
This module is part of Async iterable fun, a complete toolset of modules to work with async iterables.
This example read a text file, filtering only chunks containing a new line:
import filter from 'ai-filter';
import { createReadStream } from "fs";
const stream = createReadStream(`file.txt`, "utf8");
const result = filter(chunk => chunk.contains('\n'), fromStream(stream))
for await (const chunk of result) {
console.log(chunk);
}
The filter() method creates a new async iterable with all elements that pass the test implemented by the provided function.
