I am building a web scraping library. Below are two functions that make a request for a given url and then takes the response body (html) and loads it into the cheerio library.
scrapeListing.js
var fs = require('fs');
var request = require('request');
var cheerio = require('cheerio');

I have completed a function that takes a list and returns true if any item in the list passes the predicate test. If a predicate test is not given, the function will return true if any items in the list are truthy.

I made a basic XML parser supposed to be working in many browsers by using most older functions. What it must do is return a AST (Abstract Syntax Tree) of a XML text in string.
When it's interpreting, it's parsing the XML to generate the tree.

So, this is my function. It works, but its really really slow and the generated SQL is gargantuan and horrible to look at. It's also very expensive to run when it shouldn't be.

I am just trying to use Rust so I will be thankful for all remarks and corrections:

So a lot of people online and offline tell me that using a Listview is the most performant and I've never really understood how it works. I have instead used a <scrollview> that contains nested <PostComponent /> which I construct when an API call is made.

I often receive Excel-sheets (with empty rows) which I've to process as an Pivot-table. Because Pivot-tables don't allow empty rows I've made these script:

I have a utility class, called Bills, that extracts some information from a billId and a paymentId. I'm pasting the whole class here for completeness, you don't need to understand the algorithm behind all functions to be able to answer my question.

I have implemented a properties file reader. The goal behind creating the properties reader is to cater to different application teams to import the class and read the properties in their projects.

I wrote a script that downloads all PDFs found on the web page of a particular government agency. I would have chosen bash for such a task, but I want the script to run in Node.js. The downloaded files are a few hundred kilobytes big, if that matters.

Continuing my C++ saga, this is the third project for my CS1 class:
