object-assign | ES2015 Object.assign ponyfill | Script Programming library

I'm fairly new with React and I was trying to integrate it to my django backend. I followed two different tutorials that were quite similar but I got the same result, when I type "npm run dev", the only thing I see in my localhost is the title I changed in the html file and not the components I added on the App.js (not even the h1 tag that I'm showing here). How can I fix this?

This is the App.js:

I've been developing on Chrome, hoping that Babel simply fits my code into i.e.

And i tried to add polifills in my app.js

I want to upgrade to webpack 5. I've followed the official guide, upgraded all critical libraries (react17, babel, loaders, etc.). When launching the app, it crashes with 23 errors. 21 of them come from @babel/runtime/helpers.

A typical error looks like this:

ERROR in ../../node_modules/@babel/runtime/helpers/esm/createSuper.js 1:0-46 Module not found: Error: Can't resolve './getPrototypeOf' in '/Users/myName/Desktop/myapp/node_modules/@babel/runtime/helpers/esm'

The two other errors are:

Module not found: Error: Can't resolve 'url-loader' ERROR in FaviconsWebpackPlugin - This FaviconsWebpackPlugin version is not compatible with your current HtmlWebpackPlugin version. Please upgrade to HtmlWebpackPlugin >= 5 OR downgrade to FaviconsWebpackPlugin 2.x

Note: My html-webpack-plugin version is above 5 and favicons-webpack-plugin is the latest version as well...

Anyway, here is my webpack file:

I am trying to use react component in my HTML & javascript .So What i do I compile my react component by webpack and create a bundle file in UMD. it is working fine when I create a Hello world example.

It is working fine in below example without using state. here is working example

Now I introduce usestate in my component .I compiled below function and use is javascript it is not working.

When using vanilla js to update a DOM element's style attribute, why does object spread fail to update whilst Object.assign succeeds?

E.g., in the included code snippet, objectAssignDirect and objectAssignIndirect correctly set background-color whilst objectSpread incorrectly resets the result div's background-color.

1. Why does this happen? (is this due to cloning issues or properties such as inherited properties not being copied?)
2. Is there a way to replicate Object.assign's desired behaviour with object spread?

There are several discussions comparing Object.assign and object spread but none seem to address this strange behaviour:

• Object spread vs. Object.assign
• Object.assign vs Object Spread in Node.js

I have a case that I need to update a value in hierarchy state variable (which consists of 3 tree levels in my case, and I need to update a value in third level for example).

I copied that state variable to local variable and did the update on it, but I noticed that state variable was changed as well!

Searched for it, and saw suggestions for using Object.assign or Spread operator, I tried using the spread but it didn't help with creating a copy of the state to prevent both objects referring to the same reference but it didn't work!

Object.assign appraoch didn't work neither!

Ho can I accomplish that?

Let's assume that I've the following object:
