bower | Bower integration for your ruby/rails | Application Framework library

I am creating a selection-list, which needs to contain a list of names of persons. Currently, it looks as follows:

I am trying to get the second last value in each row of a data frame, meaning the first job a person has had. (Job1_latest is the most recent job and people had a different number of jobs in the past and I want to get the first one). I managed to get the last value per row with the code below:

first_job <- function(x) tail(x[!is.na(x)], 1)

first_job <- apply(data, 1, first_job)

I am still sort of a newbie with Laravel, and I want to install the Voyager admin panel in an existing Laravel app that is not too far along yet in development. The GitHub for Voyager is here:

Voyager Laravel Admin

The CLI is:

I would like to group array by first letter of lastnames.

For the moment I managed to classify the lastnames alphabetically but not to group them by letter

I wrote a JS code where I imported SheetJS and js-xlsx to perform actions on XLSX files (I can't use nodeJs nor npm, bower or any other solution that requires any installation on final user computer).

Shortly, the code has to do the following:

1. gets data that will be added to excel from user;
2. imports the excel the user wants to edit;
3. use a function to determine in which row data has to be added;
4. save and download a new file with updated data

The problem with the code I wrote is that it works just fine with Excels written, in fact, via Excel, but crashes if a user imports an XLSX that was previously generated and downloaded by my code.

Here's a snippet of the code:

I'm very new to Drupal and trying to install it with composer.

My composer install went well, but now, each time I try to do something, I get this error in the console :

I run this in CMD. I was trying to install gulp, but I run the wrong command:

npm install glup

Did it install some bad package, and will this harm my PC? What should I do now? I am very new to using npm so I am afraid about it.

Here are the error message display in console.

So the problem I am facing is that some packages in my package.json file required node version greater than 10. So I have nvm package installed to manage node versions and when I do node -v it gives me this: v12.19.0. So if the node version is 12.19.0 then the error shouldn't come but I think this is a global version of node so when I do npm update, this comes up:

My app works locally, however when I try to deploy to Heroku, I get a Sprockets::FileNotFound: couldn't find file 'angular' with type 'application/javascript' error.

I have tried precompiling with RAILS_ENV=production bundle exec rake assets:precompile and purging my build cache with heroku builds:cache:purge -a findum, but still no luck. I recently migrated from Bower to Yarn– not sure if my asset path is the problem?

Has anyone run into a similar error that they were able to resolve? So many thanks 🙏.

This is my application.js :
