Sync Function

The sync function can be used to bridge async functions with traditional continuation-passing style (CPS) functions. Use the sync function to create a callback with an associated Promise which can be used as a deferred result for the callback.

Example

const fs = require("fs");
const sync = require("sync");

async function asyncReadFile(file) {
    const done = sync();        // create synchronization primitive
    fs.readFile(file, done);    // pass primitive as CPS callback
    return done.promise;        // return resulting promise
}
