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:

I am getting a TypeError in this code

How to get all values from list inside a dictionary? I need to get title for every item.

I have already read the previous posts regarding this issue on stack overflow.So I know this issue is coming when you are not passing an array to deal with map function.But the problem is I already used a console.log() to check whether my passing variable is an array or not but it's already an array.Somehow I managed to solve this by changing comments to {comments} in the DishDetail function.But I need to know why I need to do an change like that to solve this issue.

This function will pass the comments array to RenderComments() function.

starting to learn JavaScript and reading the book "Eloquent JavaScript" for starters. I'm having a little difficulty understanding the factor parameter in the hummus function. Can someone help me understand what the starting value of factoris? I can see the values for the ingredient functionbut can't seem to wrap my head around the value of factor. Would appreciate the help!

I am trying to make an asynchronous function to get data from an API and use it in a FutureBuilder in Flutter. But the for loop inside the function is behaving very wierdly. It is only executing the statement just below the for loop heading.

I've been getting this error

TypeError: Cannot read property 'map' of undefined`

DISHES object is imported from dishes.js and loaded into the state object dishes in the App.js Component, then it's passed as props to MenuComponent.js through Menu component when rendered in App.js

I don't know why, everything seems correct, this is an assignment which is part of an online course and I've seen corrections made by other people who did the course and they seem to be doing the exact same thing as me and it works for them.

Output:
