convert ordered list into array in javascript

To convert an ordered list into an array in JavaScript, you can use the DOM manipulation methods to get the list elements and then loop through them to extract their values and store them in an array.

Here's an example code snippet that demonstrates how to convert an ordered list into an array:

index.tsx
let olList = document.querySelector('ol'); // select the ordered list element
let arrList = []; // create an empty array to store the list elements

// loop through the list elements and extract their values
for(let i = 0; i < olList.childNodes.length; i++) {
  if(olList.childNodes[i].nodeName === 'LI') { // check if the element is a list item
    arrList.push(olList.childNodes[i].innerText); // add the value to the array
  }
}

console.log(arrList); // output the array to the console

In this code snippet, we use the querySelector method to select the ordered list element using its tag name. We then create an empty array to store the list elements.

Next, we loop through the child nodes of the ordered list using the childNodes property of the list element. We check if each child node is a list item element using its nodeName property, and if so, we extract its inner text value using the innerText property and push it to the array using the push method.

Finally, we output the resulting array to the console using the console.log method.
