AsynchronousProgramming

See four examples and execute them. Create asynchronous analogues of Array.forEach

Parallel execution

// Array of functions
let fns = [readConfig, selectFromDb, getHttpPage, readFile];

// Call example
parallelAsync(fns, () => { console.log('Done'); });

// Implementation
function parallelAsync(fns, done) {
  // TODO: implement parallel ecexution
};

Sequential execution

// Array of functions
let fns = [readConfig, selectFromDb, getHttpPage, readFile];

// Call example
sequentialAsync(fns, () => { console.log('Done'); });

// Implementation
function sequentialAsync(fns, done) {
  // TODO: implement sequential execution
};
