Create a task scheduler which accepts a list of task, schedules them based on dependencies

const tasks = [
  { "id": "a", "dependencies": [], action: function(){setTimeout(() => console.log("Executed a"),1000)} },
  { "id": "b", "dependencies": ["a", "c"], action: function(){setTimeout(() => console.log("Executed b"),1000)} },
  { "id": "c", "dependencies": ["a"], action: function(){setTimeout(() => console.log("Executed c"),1000)} },
{ "id": "d", "dependencies": ["e"], action: function(){setTimeout(() => console.log("Executed d"),1000)} },
{ "id": "e", "dependencies": ["b", "c"], action: function(){setTimeout(() => console.log("Executed e"),1000)} },
{ "id": "f", "dependencies": ["d"], action: function(){setTimeout(() => console.log("Executed f"),1000)} }
]
// Output: 
// Executed a
// Executed c
// Executed b
// Executed e
// Executed d
// Executed f"
 */

I was asked the above in an interview and I could not solve it in the limited time. Even now I do not how to solve it.
I cracked the dependency part during the call itself, and the output was as expected. But the interviewer expected the output to be shown in the same delay as mentioned in the setTimeouts. So each after 1 second.

Adding my attempt here so it could help anyone in need. I attempted the second part of the question many times later, but they would all get printed together always.
Any help is appreciated:

const schedule = async (tasks) => {
  let nextTask = null;
  const nextTaskIndex = tasks.findIndex(({ id, dependencies }) => {
    return dependencies.length === 0;
  });
  if(nextTaskIndex === -1){
     return;
  }
  nextTask = tasks[nextTaskIndex];
  //Call
  nextTask.action();
  
  //Remove from tasks
  tasks.splice(nextTaskIndex, 1);
  const nextTaskId = nextTask.id;
  tasks.forEach(({ id, dependencies }) => {
    let foundIndex = dependencies.indexOf(nextTaskId);
    if(foundIndex !== -1)
      dependencies.splice(foundIndex, 1);
  });
  schedule(tasks);
};

Hi everybody! Like I've just written in the title I was searching for a way to practice those coding problems that you could find in a junior interview. Do you know any site where there are this kind of problem-solving riddles?

Thank you!

JavaScript and JQuery by Jon Duckett and Eloquent JavaScript by Marijn Haverbeke are two of the best books for JavaScript but they are little dated considering JavaScript: The Definitive Guide has latest 2020 edition, does anyone know when will there be a updated edition for this books
