Question

is there a function that would add a time delay between 2 lines of code. Not the settimeout, because settimeout requires a function/object in its arguments.

I am looking for something like this pseudo code

write "abc";
delay(500);
write "xyz";

TIA

Edit:
jimr’s solution in my other thread worked for my purpose, and so is Robusto’s.

I am just wondering why the “sleep” methods given by Robusto and CMS’s link are not preferred. How would that be different than the settimeout method since they both introduce a pause in the code? (settimeout pauses before the function is executed, the sleep method pauses before the next line is executed.)

Answer 1

The following is clunky and ugly and I would never do it in my own code and I DO NOT RECOMMEND IT AT ALL, but it shows that such a thing is possible.

// time arg is in milliseconds
function delay(time) {
  var d1 = new Date();
  var d2 = new Date();
  while (d2.valueOf() < d1.valueOf() + time) {
    d2 = new Date();
  }
}
