Nodejs Function Call times(f, context)

Method Source Code

// Invoke the function f this many times, passing the iteration number
// For example, to print "hello" 3 times:
//     var n = 3;
//     n.times(function(n) { console.log(n + "hello"); });
Number.prototype.times = function(f, context) {
  var n = Number(this);
  for(var i = 0; i < n; i++) f.call(context, i);
};

// Define the ES5 String.trim() method if one does not already exist.
// This method returns a string with whitespace removed from the start and end.
String.prototype.trim = String.prototype.trim || function() {
  if (!this) return this; // Don't alter the empty string
  return this.replace(/^\s+|\s+$/g, ""); // Regular expression magic
};

// Return a function's name. If it has a (nonstandard) name property, use it.
// Otherwise, convert the function to a string and extract the name from that.
// Returns an empty string for unnamed functions like itself.
Function.prototype.getName = function() {
  return this.name || this.toString().match(/function\s*([^()]*)\(/)[1];
};
