Loop through functions in Javascript

I'm not sure I fully understand your question. Perhaps this code will help?

function myFunction1() {
    // Some code you want to execute
    setTimeout(myFunction2, 1000);
}

function myFunction2() {
    // Some more code you want to execute
    setTimeout(myFunction3, 1000);
}

function myFunction3() {
    // Some final code you would like to execute before repeating the chain
    setTimeout(myFunction1, 1000);
}

Each function executes some code before calling the next function (after a 1000ms delay). myFunction3() will call myFunction1() and repeats the chain.

First of all it may be an array of functions:

// the list of functions
const actionList = [];

// pushing functions to the list
actionList.push(func1);
actionList.push(func2);
...

// running functions in a loop
for(let i = 0; i < actionList.length; i++) {
  actionList[i]();
}

If you want to run them in series with some delay, you may use simplest recursive timer approach:

const run = function (actionList, index, delay) {
  setTimeout(function () {
    actionList[index](); // execute current index function immediately
    index++; // increment index...
    if(actionList[index]) { // ...while there are items in the list
      run(actionList, index, delay); // next index function will be executed after "delay" ms
    }
  }, delay);
}

run(actionList, 0, 1000);
