yahoofinance | Yahoo Finance Service - A Java-based API | REST library

I'm using an API to retrieve data on some stocks and I would like to add a column named symbol with the query values but I'm getting an error SyntaxError: Unexpected token '[' in this.result.[i].push.... Is there any other way to do call the i-th element and pass the query data or is the syntax just wrong?

The rest of the code is just me saving the output as CSV file

This is the code:

I'm trying to implement code from https://github.com/sstrickx/yahoofinance-api on Eclipse in Java. When I run the program, I'm getting a several lines of errors that are being printed on the console. When I click on the errors, it takes me to a window named "YahooFinance.class" on Eclipse that says "Source not found." It asks me to change the attached source. I have added the source to C:/Program Files/Java/jdk-11.0.11/lib/src.zip on my computer, but I'm still getting the same error. Any help would be greatly appreciated!

Edit: This is the code that I am trying to compile from source:

I'm following book from professor Subramaniam. In the book professor is trying to explain principle of Delegating Using Lambda Expressions.

We used lambda expressions and the strategy pattern to separate a concern from a method. We can also use them to separate a concern from a class. From a reuse point of view, delegation is a better design tool than inheritance. With delegation it’s easier to vary the implementation we rely on, and we can plug in a different behavior more dynamically. This can help vary the behavior of classes independent of the behavior of the parts they depend on, and make the design more flexible without forcing a deep class hierarchy

Here is a particular class with static method which does the required calculation/fetching of information.

I'm working on a Google Sheet to track my stock portfolio. I use the googlefinance function to retrieve a stock price or last day change, but learned that it does not support all exchanges that I trade on.

I then thought to write a wrapper called simply finance, passing off the fetching of prices to Yahoo Finance in case the exchange isn't supported by Google. The wrapper would also give me the flexibility to make my sheet a bit more clean as well. For instance, Google and Yahoo use different indicators for stock exchanges. For instance, the Hong Kong Exchange is HKG on Google but HK on Yahoo. I would just like to type the exchange code that I use, and handle it in the wrapper. Here's an array with examples:

I am making a project where I want to use darta from yahooFinance. I have found this project https://www.npmjs.com/package/yahoo-finance. I have also used the basic sapper template.

Basically what I am trying is to retrive data from YF and show them on the FE.

I gave this piece of code:

I am working on setting up a MYSQL database to store stock market data. Below is data structure for database.

I have been trying to make this using instructions from this tutorial, but am having trouble getting the "daily_price" table to actually update. It is getting hung up at the data_vendor_id input which it is supposed to get as the 'id' from the "data_vendor" table. My guess is the data_vendor table is not getting complete data because when I look at it in PHP my admin it starts at id 3, but I cannot force it to collect all data.

I asked this question earlier and it got associated with this question ( How do I return the response from an asynchronous call? ) But It doesn't resolve my problem

i am very new to node.js and i'm having some error that i can't deal with or find any help that i understand. I used express-generator to initialize the app. I'm trying to send and object i get through an api call to the front end. I wrote a class "StockClass.js" with a function makeApiCall() which makes the call and returns the object. But when i call that function in the router i get "undefined". Heres the code
