var request = require('request'); var links = ['https://google.com', 'https://yahoo.com']; for (link in links) { (function(url) { request(url, function() { console.log(url); }); })(links[link]); } |
Notice the brackets around the function(url) and })(links[link]) then passes the link to that function.
Check out the [source]/source if my explanation doesn’t make sense. (Please let me know too)
