I recently learned that the AbortController in JavaScript has built-in timeout functionality.

This means that you don't need to handle timeouts manually using setTimeout and clearTimeout, but can easily create a timeout signal when fetching data, for example.
Code snippet showing AbortSignal.timeout usage with fetch API. Creates a 5-second timeout signal, makes a fetch request that converts response to blob, and handles TimeoutError in catch block.

My #AdventOfCode solution for Day 03 written in #ElixirLang.
Elixir code that extracts multiplication operations from text. It finds patterns like 'mul(number,number)', captures the numbers, converts them to integers, multiplies each pair, and sums all results. Elixir code that processes a string using regular expressions. It scans for patterns of either multiplication operations in the format 'mul(number,number)' or toggle commands 'do()' and 'don't()'. Using Enum.reduce, it maintains a running count and status. When 'do()' is found, it enables processing, while 'don't()' disables it. When enabled and a multiplication pattern is found, it multiplies the two numbers and adds the result to the count. When disabled, it skips multiplication operations. The final count is extracted using elem(0).
