Turns synchronous functions into promise-based
- Allows to write promise-based code in syncronous manner
- Supports any function arity
npm install function-promisify
var promisify = require('function-promisify');
var multiply = promisify(function (number, multiplier) {
return number * multiplier;
});
var log = promisify(console.log);
// Here we can treat existing and future values in exactly the same manner
log(multiply(100, 3));
log(multiply(Promise.resolve(200), 4));
log(multiply(300, Promise.resolve(10)));
log(multiply(Promise.resolve(400), Promise.resolve(5)));
