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:

I have used the below code:

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 -

I'd like to do something like this:

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:

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:

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:

create.html page

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:

1. Extract the recipe object included in the POST request body
2. Generate a unique ID for the new recipe (Etc. a basic integer that increases every time a recipe is added.)
3. 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):

load recipe in cmd

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:

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

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.
