In this chapter, we came to know that promises are getting more easy to use within Node.js. The following is the set of all major utilities offered by Q for using Node.js:
Q.nfapply(fs.readFile, [filename, encoding]).then(console.log);Q.nfcall(fs.readFile, filename, encoding).then(console.log);Q.nfbind(fs.readFile)(filename, encoding).then(console.log);Q.npost(fs, "readFile", [filename, encoding]).then(console.log);Q.nsend(fs, "readFile", filename, encoding).then(console.log);
Q has more to offer, but the preceding ones are the best and most used and sensible use of these can help us write a more manageable, cleaner, and dynamically controlled mechanism.
