Day 14: August 07, Tuesday

Today ‘s Progress: I finished the challenges in Object Oriented Programming section and started Functional Programming Challenges.

Thoughts: Oh no these FCC_Challenges are not at all straight forward, and there are no hints or examples it’s very challenging and not a lot of fun Thank goodness there is google! You can really tell the folks who did the last round of challenges cared about passing on information rather than this round of challenges designed to trick the student and make things obscure and nerve wracking. Today it was all about dealing with these frustrating misleading challenges yuck!

//Implement map on a Prototype
//Write your own Array.prototype.myMap(), which should behave exactly like Array.prototype.map(). You may use a for loop or the forEach method.
// the global Array
var s = [23, 65, 98, 5];
Array.prototype.myMap = function(callback){
  var newArray = [];
  // Add your code below this line
   for (let i = 0; i < this.length; i++) {
     newArray.push(callback(this[i]));
  };
  // Add your code above this line
  return newArray;
};
var new_s = s.myMap(function(item){
  return console.log(item * 2);
});
console.log("-------------------Next------------------------");

This one took a few google searched and trying to figure out callback…
