Navigating these links among parents, children, and siblings is often useful, as in the previous function, which runs through the whole document.But if we want to find a specific node in the document, reaching it by starting at and blindly following a hard-coded path of links is a bad idea.It takes as arguments two nodes: a new node and the node to be replaced.The replaced node must be a child of the element the method is called on.For each box, there is an object, which we can interact with to find out things such as what HTML tag it represents and which boxes and text it contains.This representation is called the serves as the root. In addition to representing recursive structures such as HTML documents or programs, they are often used to maintain sorted sets of data because elements can usually be found or inserted more efficiently in a sorted tree than in a sorted flat array. The syntax tree for the Egg language had variables, values, and application nodes.The browser builds up a model of the document’s structure and then uses this model to draw the page on the screen.This representation of the document is one of the toys that a Java Script program has available in its sandbox. It acts as a The data structure the browser uses to represent the document follows this shape.
However, the original idea that I had was to break down some of the repetitive sections into their own function and use those new sub-functions as part of the main one.The following diagram illustrates these: property that points to an array-like object holding its children.
