JavaScript Microtasks: A Developer's Guide

What Are Microtasks and Why Should You Care?

As a JavaScript developer, you're likely familiar with the event loop handling asynchronous operations. However, microtasks provide a crucial middle layer between synchronous code execution and the macrotask queue that can significantly impact your application's behavior.

Think of microtasks as high-priority tasks that JavaScript executes immediately after the current synchronous operation, but before the next macrotask (like setTimeout callbacks) or render updates.

Common Sources of Microtasks:

  def initialize
    @index = Hash.new { |h, k| h[k] = Set.new }
  end
  
  def []=(key, value)
    trigrams(key).each { @index[it] << [key, value] }
  end

Summary

Notes to install Ubuntu 22.04.4LTS (Upgraded to 24.04LTS) up and running on my 2017 MacBook Pro 15 inch (MacBookPro14,3).

Now everything except the TouchID (Fingerprint), Suspend and Hibernation seems to work for me.

About Ubuntu 24.04LTS: I tried to install Ubuntu 24.04 and didn't have success. There was a crash issue during installation. https://bugs.launchpad.net/subiquity/+bug/2065310 But I installed 22.04 and upgraded it to the 24.04LTS later and it working same as 22.04.4.

AWS Event Driven Architecture

What is AWS Event Driven Architecture ?

• AWS Event-Driven Architecture is an approach that utilizes Amazon Web Services to build scalable and decoupled applications.
• It relies on events as the primary means of communication between components.
• The architecture includes event sources that generate events, an event bus for routing events, rules to filter and route events, and targets for actions triggered by events.
• Event Driven Architecture offers benefits such as scalability, loose coupling, flexibility, and real-time processing.
