// using wait-sync, you can use both async *and* sync code in the same execution block
// without worring about blocking the thread (so node's event-loop keeps running, I/O still works as expected etc..)

var waitSync = require('wait-sync');

// the easy part - just log "1" to the console
console.log(1);

// next, setup some async operation that will log "2" sometime in the future - say, 3 seconds from now
setTimeout(() => console.log(2), 3000);

// In older IE, this function doesn't inherit from Function.prototype
// so there's no .apply() we can use.
// This will throw an error
document.getElementById.apply(document, ['myDiv']) // Error!


// The solution:
(Function.prototype.apply).apply(document.getElementById, [document, ['myDiv']]);  // Smooth!

function greet(name){
  console.log('hello ' + name);
}


// We usually invoke a function by writing it's name followed by parenthesis
greet('John'); // hello John


// Another way - using .apply()
