Введение

Начать стоит отсюда. Не пугайтесь то, что это книга по незнакомой OS, эти термины практически везде одинаковые и здесь они изложены в понятной для начинающих форме.

http://www.qnx.com/developers/docs/6.4.1/neutrino/getting_started/s1_procs.html

Прочесть нужно треть главы до подраздела "Starting a process", если С не пугает, читайте полностью. После прочтения вы будете понимать, что такое process, thread, mutex, priorites, semaphores, scheduler, contex-switch, kernel states.

Prerequisites

1. The app that uses tailwind + external component library (CL) (but not 3rdparty, your company internal one, for example)
2. The component library also uses tailwind

The goal

To be able to purge safely unused tailwind classes from the build (https://tailwindcss.com/docs/controlling-file-size)

Solution

The idea here is simple: we're going to purge css on the app side + whitelist classes that component library is using.

const sysEvents = Application("System Events");
sysEvents.includeStandardAdditions = true;


function typeWithDelay(text, delayValue = 0.02) {
  if (delayValue) {
    for (let i = 0; i < text.length; i++) {
      sysEvents.keystroke(text[i]);
      delay(delayValue);
    }

You can convert js-code like this:

var a = '1',
    b,
    c = '2';

-   # locks secondary indexes and primary key index
-   AssignedUser.where(task_id: task.id, subtask_id: nil).delete_all
+   assigned_user_ids_to_clean = AssignedUser.where(task_id: task.id, subtask_id: nil).pluck(:id)
+   # doing delete ... where id in (...) (equality test on primary key), locks only primary key index
+   AssignedUser.where(id: assigned_user_ids_to_clean).delete_all
    task.assigned_user_ids = assigned_user_ids # inserts multiple records
  end
