Question

Is there a way to duplicate a specific quantity of icons with Polymer?

I am facing a bit of a challenge with a seemingly simple task.

My goal is to showcase the number of credits completed by each student in my list using star icons. For instance, John ★, Sarah ★★, Ken ★, and Jared ★★★★.

The JSON data containing student information is bound to each student's div, allowing access through {{student.credits}}. However, using <template repeat> doesn't appear to be an ideal solution for this scenario. I also considered adding a specific class like star2 and modifying the default icon CSS, but due to SVG usage for each icon, repetition isn't as straightforward as it would be with a standard image background.

If you have any insights or tips on how to address this issue, I would greatly appreciate your assistance!

If you're looking for a clever solution, consider implementing the technique I utilized in my rating-element web component.

Begin by creating an array with a length corresponding to the number of credits needed:
```
created: function () {
  this._credits = new Array(this.credits);
},
```

Take advantage of this array within the repeat template:

<template repeat="{{_ in _credits}}"></div>
  <div>★</div>
</template>

For further details, examine the full component found in the devel branch, specifically focusing on the template repeat and the created callback code snippets.

I have a strong interest in php and imagine it would look something like this:

For($i=0; $i <= $rating; $i++){
    echo "<img src='icons/star.png' />";
}
