JavaScript How to Select Specific Piece of HTML using JQuery?

my goal for this code is to make it so when one of the tree branches is clicked, it changes the clicked ^ from a ^ to a O using JQuery and Javascript (this is for a school assignment). For example, if I clicked the very top ^ it would replace the ^ with an O, or if I clicked the very left ^ in the second row, it would change that ^ to a O, etc. I want to try and keep it rather simple and only add on to the existing code I already have rather than replacing all of it. I am a beginner when it comes to coding in Javascript and JQuery, so please avoid super-advanced tactics. Thank you very much.

Current Code:

```
<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
  </head>
  <body>
  <h1>Welcome to the Holiday Tree Simulator</h1>
  <ul>
   <li> Click a green branch (<font color=green>^</font>) to change it into a red ornament
   <li> Click a red ornament (<font color=red>O</font>) to turn it into an unlit light (only when power is off)
   <li> Click an unlit light (<font color=gray>*</font>) to turn it into a green branch (only when power is off)
  </ul>

Answer:1

in generating tree loop, you need to replace following code

    $("#treeBranches").append("^");

with

    $("#treeBranches").append('<span class="leaf">^</span>');

it'll create every leaf as an accessible component

then following code will work to change particular leaf to ornament

    ///////////change ornament/////////////
    $(document).on('click','.leaf', function() {
        $(this).html('O');  
    })
    ///////////run newTree command////////////////
