Below File is Accessing_Children_of_an_Element.js File.
console.log(document.body.firstChild);  //Here, firstChild is textNode
console.log(document.body.lastChild);
console.log(document.body.childNodes);
// Following is always true:
//elem.childNodes[0] == elem.firstChild
//elem.childNodes[elem.childNodes.length - 1] === elem.lastChild

// There is also a method elem.hasChildNodes() to check whether there are any child nodes.
// NOTE: childNodes looks like an array but if not actually an array but a collection we can use
//Array.from(collection) to convert it into an Array.(Array methods won't work)
let arr = Array.from(document.body.childNodes);
console.log(arr);
