innerHTML to add content?

In the Video; he uses innerHTML to add content(<li>red cabbage</li>). However, is there a way to use innerHTML without destroying the previous child elements?

Hello,

sure, .innerHTML is an elements property and so it can be treated as such. You could append a <li> at the end of an <ul id='list'> using,

let element = document.getElementById('list')
element.innerHTML += '<li></li>'

this is equivalent to,

let element = document.getElementById('list');
element.innerHTML = element.innerHTML + '<li></li>'.

Note that you can also use any JavaScript string manipulation method. For example,

let element = document.getElementById('listContainer');
element.innerHTML = element.innerHTML.replace('ul', 'ol');

will make change the type of the list from unordered to ordered.

Do not forget to take a look at String.replace() combined with the magic of RegExp.

Hope that helped!
