QUESTION
My brain froze with this advanced filtering. This task has exceeded my basic knowledge of filter, map etc.
Here I have an array with nested objects with array:
...ANSWER
Answered 2021-Jun-13 at 09:21You can use reduce method of array. First find out the object inside data array and then add that to accumulator array as new entry by preserving the original structure.

I am working on a project in which I need to post a new Course to my API. I tested this with POSTMAN and API works just fine, however when I try to post data using react fetch data is corrupted. While sending single strings like dishName: "pizza" works just fine and is shown in database I cannot manage to send an array of objects. I tried to do it in many ways like:
...ANSWER
Answered 2021-May-27 at 21:44You are setting the ingredients state as a string, so you are basically 'stringify' a string which will result in JSON SyntaxError. If you want to send an array that way you must specify the array bracket [ and ] in order to make it a valid array.
To solve it just change:

So I have 3 tabs set up pretty much exactly like this - https://www.w3schools.com/howto/howto_js_tabs.asp - but the content under each tab is a different video (HTML). My problem is that after changing tabs, the video/audio from the previous tab continues to play - unless I pause the video prior to switching tabs. I've tried a few of the different solutions I've seen for problems similar to this, but still can't find a solution that works on my page.
Here is the HTML I have -

QUESTION
I'm making a flappy bird-like game. The problem is, the images do not load in the loop within the draw() function. If I were to put the drawImage()'s outside of the loop (like the rest of the images), then they would work.
No errors in the console, the two images inside the for loop do not appear and I just don't understand why >:/
HTML:
...ANSWER
Answered 2021-Mar-27 at 15:09First and most importantly: you're mixing two completely different things here.
QUESTION
I'm following a tutorial on a flappy bird game by freeCodeCamp https://www.youtube.com/watch?v=pufKO5EG8nc
But I'm doing it using a class to learn more about it.
The problem is, the images do not load, while in the video they load fine.
I googled around and learned of the onload event, implemented it in there, but still no bite, and no error messages in the console.
Even without the onload events, why does the video's images load, but mine don't? >:(
My HTML code:
...ANSWER
Answered 2021-Mar-26 at 16:19Your problem has to do with the scope - which refers to the accessibility of variables, objects and functions - and the meaning of the this keyword depending on the actual scope.
To get a better understanding let's have a look at the following example:
QUESTION
I'm new to Javascript and I'm trying to learn express and create an application that will allow users to create new recipes, browse existing recipes, and view recipes.
I've got my server running by typing recipeserver.js in the cmd bar and then typing localhost:3000 in my address bar on google chrome. So far it loads the index.html homepage and from there, I am able to click on a link titled "Create a Recipe" which leads me to the create.html page that looks like this:
Initially, there will be only three recipes on the server, which are included in the database object within the recipeserver.js code I've included below. The create.html page allows a user to enter recipe information. When the Save Recipe button is clicked, the addrecipe.js file is supposed to send the recipe data to the server using a POST request to the resource /recipes
Within the server code, all recipes will be stored in a single object called database. The keys of this object will be unique IDs and the values will be the recipes associated with those IDs. I'm stuck on a task where I'm supposed to add a route within the server code to handle POST requests to the /recipes resource. The handler for this route should:
- Extract the recipe object included in the POST request body
- Generate a unique ID for the new recipe (Etc. a basic integer that increases every time a recipe is added.)
- Add a new entry into the recipes object with the key being the unique ID and the value being the recipe object.
When testing my code by adding a few recipes to my server, I should be able to just log the contents of the recipes object to see that it is storing the correct data, like in the picture below (this picture isn't mine):
So as shown in the first picture of my screen, I filled in the contents of the recipe I want to add in create.html. When I click on the "Save Recipe" button however, instead of loading the contents of the recipe into my cmd window, I get the error:
...ANSWER
Answered 2021-Mar-14 at 17:45First of all, thanks for putting in effort in explaining your issue in detail. One suggestions, you can share the repo instead of snippets of code (since this is quite long, and structure of folder do affects how we can get it up running).
Nonetheless, the error you're getting is due to recipes in recipes.pug is actually undefined.

QUESTION
people! I'm trying to code a Space Invaders Python program to learning purposes but keep stumbling in list and data manipulation issues inside loops. I just created a Class Squid to envelope the data for a circle to PyGame in the form: RGB, [X,Y] int
...ANSWER
Answered 2021-Feb-14 at 00:53Here's my suggestion:
Use a class Squid as a blueprint for squids and create squid instances from your class. Each squid instance has a position, a radius (with a default if you don't specify it) and a color (also with a default).
We then generate new squids and add them to a list, our squad. While doing so, we use the iteration index as our respective X position, while keeping the Y value constant - just for the sake of example.
QUESTION
Using the w3schools.com SQL tutorial Northwind database, I'm trying to display the category that has the most products shipped. Additionally, I want to display the net income from all sales in that category. I can't figure out how to take the category with the most products shipped, and use the amount of products shipped to calculate the net income of that category. This is because there are many different products that have the same CategoryID but different prices.
...ANSWER
Answered 2021-Jan-25 at 07:24So first of all you get the income for each product and category and then based on that you find total income for that category and you do this with the help of subquery, then you join this resultant table with the category table and with the help of group by you find the product count and total income for each category, below is the sql query for more indepth understanding
