Is there a way to defer a for loop in Angular?

In my Angular project, I am working on a sorting visualizer using the chart.js bar chart. Currently, I am focusing on visualizing bubble sort and I want to incorporate a delay in each iteration of the inner loop. I assume you are familiar with the loop structure of bubble sort. My plan is to compare the elements, then call a custom draw function to update the chart, and finally introduce a 0.5 second delay before moving on to the next iteration.

for (let i = 0; i < this.data.length; i++) {

      for (let j = 0; j < this.data.length; j++) {
          //comparison
            this.draw();
          // 0.5 SECOND DELAY
      }

}

There may be more efficient ways to handle the event loop in javascript, but here is a starting point: Check out this jsfiddle example: https://jsfiddle.net/zdfo5tce/

var data=[1,2,3,4,5]
var counter=0
let draw=(c) => document.body.innerHTML=c;

for (let i = 0; i < this.data.length; i++) {

      for (let j = 0; j < this.data.length; j++) {
          //comparison
            setTimeout(draw.bind(this, counter), ++counter*500);
          // 0.5 SECOND DELAY
      }

}

the delay for each iteration is set to 500 milliseconds

for (let x = 0; x < this.content.length; x++) {
      for (let y = 0; y < this.content.length; y++) {
           setTimeout(function(){
             this.display();
}, 500 * y);
      }
}
