function exerciseOne(names){
// Exercise One: In this exercise you will be given and array called names.
// Using the forEach method and a callback as it's only argument, console log
// each of the names.
}
function exerciseTwo(cents){
// Exercise Two: In this exercise you will be given an array called 'cents'
// This array is a list of prices, but everything is in cents instead of dollars.
// Using the map method, divide every value by 100 and save it as a new array 'dollars'
// Please write your answer in the lines above.
return dollars;
}
This is what I have:
function exerciseOne(names){
// Exercise One: In this exercise you will be given and array called names.
// Using the forEach method and a callback as it's only argument, console log
// each of the names.
console.log(names);
}
function eachMethod(array, cb){
for(let i = 0; i < array.length; i++){
cb(array[i]);
}
}
console.log(names.forEach(exerciseOne));
function exerciseTwo(cents){
// Exercise Two: In this exercise you will be given an array called 'cents'
// This array is a list of prices, but everything is in cents instead of dollars.
// Using the map method, divide every value by 100 and save it as a new array 'dollars'
return cents / 100;
}
dollars.map(exerciseTwo);
// Please write your answer in the lines above.
return dollars;
}
What did I do wrong?
This was the model solution to exercise two as well:
function exerciseTwo(cents){
// Exercise Two: In this exercise you will be given an array called 'cents'
// This array is a list of prices, but everything is in cents instead of dollars.
// Using the map method, divide every value by 100 and save it as a new array 'dollars'
const dollars = cents.map(function(price){
return price/100;
})
// Please write your answer in the lines above.
return dollars;
}
For Anyone wondering this is the way they actually wanted you to do problem 1. The syntax is weird it took me like 3 days to figure out. It frustrated me and i didn't want to use the "elem=>" method because it wasn't covered in curriculum. Make sure you guys are watching your braces and parenthesis smh.. Anyways, here ya go:
function exerciseOne(names){
// Exercise One: In this exercise you will be given and array called names.
// Using the forEach method and a callback as it's only argument, console log
// each of the names.
names.forEach(function(names){
console.log(names);
}
);
}
Study these examples: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach
And:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map
Note that the map example can be written:
var array1 = [1, 4, 9, 16];
// This function doubles the input value and returns it
function doubler(x) {
return x * 2;
}
// pass the function to map
const map1 = array1.map(doubler);
console.log(map1);
// expected output: Array [2, 8, 18, 32]@malvoliothegood Thank you sooo much!!!
Exercise One:
It ask you to console.log each individual element, not the entire array:
Exercise Two:
You are doing code that makes no sense. You have to do this:

@vedprad1 Thank you soooooo much!!!
@vedprad1
maximussallam (2)'s questions could be homework questions so it is best not to give him/her the answers, rather point them in the right direction or give them a similar example.
@vedprad1 in the youtube video and material we are given before performing this assignment it does not make any mention of using "elem =>". My question would be how would we have known to use this => to get the correct answer? Did I miss something?
edit: after messing around for with it for awhile, it tells me that this is a correct answer:
function exerciseOne(names){
// Exercise One: In this exercise you will be given an array called 'names'.
// Using the forEach method and a callback as it's only argument, console log
// each of the names.
names.forEach(function (names){
console.log(names);
}
)}
