bookmarker | Bookmarks on terminal | Command Line Interface library

I'm trying to learn ElectronJS right now from the book "Electron in Action" (https://www.amazon.com/Electron-Action-Steve-Kinney/dp/1617294144/).

The bit of code I'm having difficulty with is one in which I am, through JS code within

And this is the code for the Main process:

I do not get the desired output when running the following electron app i.e alert box containing pwd as output. However, the commented line inside index.html seems to work fine. The developer console of the chromium window says "Uncaught ReferenceError: __dirname is not defined at HTMLButtonElement.". This snippet is taken verbatim(except the commented line) from the book "Electron in action" by Steve Kinney 2019 edition.

any suggestions?

package.json is as follows

What I'm doing now is a form takes the website name and the URL. When I click on the submit button, the output is the name of the website and two buttons: 1. one to visit 2. remove the bookmark onClick

Unfortunately I can't make the remove button function:

Trying to create a bookmark app in Javascript. I created a bookmark object and an empty array "bookmarks" to store the website name and website url. However clicking on the submit doesn't populate the bookmark array. It replaces the initial value with the new value in the input form

I have a problem to scrape specific element text from this webpage:

https://www.oddsportal.com/soccer/africa/africa-cup-of-nations/benin-togo-IsfnZDFd/

This is url for a specific match in archived results and I need to scrape odds from 4 bookmakers on this page. I have thousands of match url's which I want to scrape. The code looks like this:

This is what I tried to find the bookmaker odds but it does not work:

As you know, soccer odds results/history had no end. I want to generate output like this. What is the best practise to design mysql database?

This is what i got so far:

I'm building an app with ES5 JS just for practice and "fun" where I store websites in localStorage then print them out on the page, i.e. a bookmarker application.

I'm getting a

TypeError: Cannot set property 'innerHTML' of null

error in the console when I run the following code:

I am doing an app with User, Article and To_do_list

I am using the gem bookmark_system to add a bookmark to an article. https://github.com/pmviva/bookmark_system

The list of the bookmarked articles is what I am going to show in the To_do_list.

I want each user to have only 1 To_do_list. I also want users to be able to check other users to_do_list.

This is a piece of code from a simple Bookmarker App I made. I am kind of confused about something here.
Look at the 3rd line of the code. Isn't there supposed to be == instead of = after classname?
Because = is an assignment operator. What I need is true which == or === should give and it indeed does from the console.log.

However when I use === inside the if statement the function no longer works. But it works with the = which is not making any sense to me. It would be great if someone could clarify what's the problem here.
