node.js/ strings which meet regex

Question

I have a list of string in node.js

var listStr = ["helloworld","helloworld1","helloworld2","somethingelse"]

I want to find all strings which meet some regex. For example, for the regex: *world*, I would get the next strings: "helloworld","helloworld1","helloworld2"

there is any npm package or function which get a list of strings and regex, and return the strings which meet the regex?

You don't need an NPM package for this:

var filtered = listStr.filter(function (item) {
    return item.match(/world/);
});

Contents of filtered:

[ 'hello world',
  'helloworld1',
  'helloworld2' ]

You can do this in plain JavaScript. Just fix your regex, and use Array#filter():

listStr.filter(function(str){return /.*world.*/.test(str)})
