Backstory (skipable):
Hello, I'm a student at Lambda school. Recently we had a JS assessment test in order to progress to the next unit, but I wounded up flunking it twice. So now I have to repeat Unit 1. I'm here today in order to finally knock out that damn exam. I don't have a problem working with Arrays or Objects, what I do have a problem with is figuring out a way to solve issues when they are combined. It's like: "What the hell, do I use map or Object.Key?" Those types of problems appeared throughout the exam. It's fine to challenge students, but I never worked with both at the same time before. The approach was completely lost on me and before I knew it, my 3 hours were up two days straight.
What I hope you can provide:
I'm going to provide one problem and show you the work that I did. What I would like is for you to formulate pseudo code for me to work out that problem. I need to learn how to use Pseudo code if I want to be a good web engineer. Please do not solve the problem for me, all I ask is pseudo code. I'll try to work on the problem based on the pseudo code I feel is manageable for me to do. Thanks in Advance.

How I would approach the problem (Pseudo Code):
//Create a variable called starship2nd
//Assign starship2nd the 2nd starship of each character.
//Check the length of the 2nd starship of each character. [[I'm stuck on this phase.]]
//Return 'none' after the checker function iterates through the Object's array. [[[Not sure how to do this part either..]]
Failed Solutions (Are they repairable? O_O)
solution 1 (failed)
const starship2nd = character.starships[1].name
const shipLength = starship2nd.length
function checkLength () {
if (shipLength === 0) {
return 'none'
}
return checkLength()
Thank you for your time. ^_^
Here is some pseudo code for you
if (character has property 'starships' and it is an array) {
if (length of starships is at least 2) {
return name property of second starship
} else {
return none
}
} else {
return none
}
You might think that some of those checks are overkill and not necessary since you know your input, but it is always good practice to double check properties and lengths before you begin accessing and assuming.
I hope that helps you with reasoning about the problem.
I have a universal variable on my website which includes line items with relevant details. These line items are reflective of what the user has in their cart. I am integrating with a third party who require the data passed through to them to be formatted slightly different. The below is the data layer currently on my website:
"lineItems": [
{
"product": {
"id": "s83y016b5",
"sku_code": "s83y016b5",
"url": "/en-gb/jeans/p/s83y016b5",
"image_url": "http://www.my-website.com/a/p/shirt.jpeg",
"name": "Jeans",
"manufacturer": "",
"category": "Everyday Wear",
"stock": 116,
"currency": "GBP",
"unit_sale_price": 16,
"unit_price": 16,
"size": "6-9 Months",
"color": "Indigo"
},
"quantity": 1
}
]
The below is what format the third party needs:
"lineItems": [
{
"sku": "s83y016b5",
"name": "Jeans",
"description": "A super great pair of jeans.",
"category": "Everyday Wear",
"other": {"fieldName": "This can be a string or any value you like"}
"unitPrice": 11.99,
"salePrice": 11.99,
"quantity": 2,
"totalPrice": 23.98
"imageUrl": "http://www.my-website.com/a/p/shirt.jpeg",
"productUrl": "http://www.my-website.com/index.php/shirt.html",
}]
Obviously this needs to be dynamic based on the products in the cart. What I intend to do is use javascript to amend the data and send this to the third party via Google Tag Manager.
Any help would be greatly appreciated. Any questions welcome.
This should be close to what you're looking for.
let oldLineItems = "your object";
let newLineItems = {};
newLineItems.lineItems = [];
for (let i in oldLineItems.lineItems) {
newLineItems.lineItems[i] = {};
for (let key in oldLineItems.lineItems[i].product)
{
newLineItems.lineItems[i][key] = oldLineItems.lineItems[i].product[key];
}
}
See code below.
I'm not sure how your lineItems object is set up, but below I just created an array called line Items. If line items is a key in an object which I suspect from your snippet above, you will have to go a level deeper in the for loops used in my example below.
Simply add further details to the new object in the nested for in loops below.
var lineItems =
[
{
"product": {
"id": "s83y016b5",
"sku_code": "s83y016b5",

},
"quantity": 14
},
];
var newLineItems = [];
for(var char in lineItems){
// Adding some values to newLineItems.
newLineItems.push({
sku: lineItems[char].product.sku_code,
name: lineItems[char].product.name,
description: lineItems[char].product.description,
category: lineItems[char].product.category,
quantity: lineItems[char].quantity
});
}
console.log(JSON.stringify(newLineItems));
Actually i want to add "is_promoted" field in the response according to the result of elastic search if the "doc_count" is 1 then i have to fetch the id of the property and "is_promoted" flag from the actual result(Which you can see at the question).Its like a post filter in the elastic search. but i want add condition in the post filter. please see the current and expected output.
And below is the current output of the elastic query
{
"total_records": 32392,
"fetched_records": 3845,
"result": [
{
"key": "dp3w",
"doc_count": 343,
"centroid": {
"location": {
"lat": 41.919059987131064,
"lon": -87.71653202438385
},
"count": 343
}
},
{
"key": "djvw",
"doc_count": 1,
"centroid": {
"location": {
"lat": 33.49416188221888,
"lon": -82.0443208285174
},
"count": 1
}
},
{
"key": "9qhs",
"doc_count": 1,
"centroid": {
"location": {
"lat": 34.52696419113244,
"lon": -117.29711956000672
},
"count": 1
}
}
]
}
So i want to add field "is_promoted" if the "doc_count" is 1 and below is the expected output
{
"total_records": 32392,
"fetched_records": 3845,
"result": [
{
"key": "dp3w",
"doc_count": 343,
"centroid": {
"location": {
"lat": 41.919059987131064,
"lon": -87.71653202438385
},
"count": 343
}
},
{
"key": "djvw",
"doc_count": 1,
"is_promoted":true,
"centroid": {
"location": {
"lat": 33.49416188221888,
"lon": -82.0443208285174
},
"count": 1
}
},
{
"key": "9qhs",
"doc_count": 1,
"is_promoted":true,
"centroid": {
"location": {
"lat": 34.52696419113244,
"lon": -117.29711956000672
},
"count": 1
}
}
]
}
I used aggregation for that.
query.bool.minimum_should_match = 1;
aggQuery.zoomedin = {
filter: {
geo_bounding_box: {
location: {
top_left: {
lat: params.geo_bounding_box.location.nw.lat,
lon: params.geo_bounding_box.location.nw.lng
},
bottom_right: {
lat: params.geo_bounding_box.location.se.lat,
lon: params.geo_bounding_box.location.se.lng
}
}
}
},
aggregations: {
result: {
geohash_grid: {
field: "location",
precision: zoomLevel
},
"aggs": {
"centroid": {
"geo_centroid": { "field": "location" }
}
}
}
}

Okay, so, from the discussion in the direct comments under your OP I understand that you only want to add is_promoted field to some of the objects in the result array of the ES response, according to a certain condition.
What you need to do is very simple: loop through the result array, check the condition for each object and add the property.
for (const obj of elasticSearchResult.result) {
if (+obj.doc_count <= 1) {
obj['is_promoted'] = true;
}
}
I add the + sign in front of the obj.doc_count to ensure it's parsed to int and thus conducting a proper conditional comparison. The is_promoted property is added as an array key to ensure there are no compile or runtime errors of the sort of Property does not exist, since we create a new property in the object.
I don't know why do you use this aggregation functionality. You problem is purely JavaScript related and has nothing to do with ES or Node.js in particular.
P.S. This solution is based on the fact I understand your question correctly. Otherwise, please extend or improve your OP.
Is there a way to display the current number of members of my Facebook group on a SquareSpace code block (which only accepts HTML and JavaScript)?
Totally.
You can use Facebook Graph to accomplish what you want. Using an ordinary HTTPS request, I got this JSON-formatted results :

I'm trying to figure out how to retrieve Youtube Tags and use them in my code behind, but I can't even seem to retrieve any information whatsoever. What would be the best way to retrieve tags with a delimiter like a , or a ; ?
var video_id='VA770wpLX-Q';
$.getJSON('http://gdata.youtube.com/feeds/api/videos/'+video_id+'?v=2&alt=jsonc',function(data,status,xhr){
