Inside the given ul element, there are four li child elements. If the code below is run in the console:
var a = document.getElementsByTagName("ul")[0];
a.childNodes.splice(1, 2, "abc", "cde");
An error will appear with this message:
TypeError: a.childNodes.splice is not a function
Can you identify the issue in this scenario?
Node.childnodes retrieves a Node List, which differs from an array in JavaScript. Therefore, the splice method cannot be applied to it.
According to MDN,
Why is NodeList not an Array?
Although NodeList objects are often used similarly to arrays and may lead you to believe that applying Array.prototype methods would work on them, NodeList objects do not possess the typical Array methods.
To overcome this limitation, you can convert it into an array like so:
var nodesArray = [].slice.call(a);
//next, utilize the splice method.
nodesArray.childNodes.splice(1, 2, "abc", "cde");
