I have to make a program which checks two txt files and concatenates the lines which start with the same ID. The results must be in a new file The files are in the following format:

ID STRING_UP_TO_30_CHARS

Error checking is not necessary but I have been stressing over this for quite a while now. I'm pretty new to programming in general as I am a freshman in University.

Code that I have right now:

I have two ejs forms that when hit, make an HTTP post request to my /api/users/makePicks/:id route. This route hits my controller which updates the Users model in my mongodb with the NFL picks they submitted in the EJS form.

I need this route to create the picks object for each route if they do not exist for that particular week, and if they do exist it needs to update the picks that are already there. The picks are being stored in my User model in an array, this array contains objects for each weeks picks. Currently the code, with much help from Mohammed, is successfully pushing code to to array. But i cannot seem to figure out how to update the picks if an object with a key of that week exists.

My validation is finally working properly. What I mean is we are running a for loop on the picks array, it will console.log true if there is already a matching picks object with for that weeks picks, if the object with a first key value with the current weeks form doesn't exist, it will console.log false and push the new picks to the array.

The only part that isn't working is the if statement nested within my for loop, it is not updating the object if it already exists in the picks.array. But as I said, the validation is working correctly. I suspect the line of code

Today, I'm trying to get the list of javascript index based from the selected data id that I have.

I'm following this guide from https://buefy.org/documentation/table/#checkable where it needs something like this: checkedRows: [data[1], data[3]] to able to check the specific row in the table.

What I need to do is to check the table based from my web API response.

I have this sample response data.

I try to get data from my Api, I can get data and convert it into an object class I created and show it but I can't store all objects instances in an list. Someone knows ? I tried to add every element I got in a List then try to get elements from it after but doesn't work, the list stays empty. This is what my API returns :

i am trying to create the driver performance assistant.

when i start up the page it needs to read the variable from the last time and use that to count up. (i have created a dashboard that reads data through a plugin from a game. i am trying to create the driver performance assistant from DAF (truck brand). the way it should work is when rolling out the vehicle it counts up a variable accordingly to the time it is rolling out (this part i have created and it works) now my problem is. i am also trying to save it in the localstorage so it wont get lost. but the variable is doing weird things when i tries to read the localstorage data. this code only needs to be in javascript.

I have a dataset for itemset mining. I want to find occurences of each unique number i.e. Candidate 1 itemsets.

The shape of the data is 3000x1. I'm unable to figure out how to count the unique occurences.

List of distict values of the data are stored.

Using the ndarray distinct, how can I find the frequency of each item in the dataset?

Update Got the solution with @jojo help.
