Web/API/Node/normalize

The Node.normalize() method puts the specified node and all of its sub-tree into a "normalized" form. In a normalized sub-tree, no text nodes in the sub-tree are empty and there are no adjacent text nodes.

Syntax

element.normalize();

Example

let wrapper = document.createElement("div");

wrapper.appendChild( document.createTextNode("Part 1 ") );
wrapper.appendChild( document.createTextNode("Part 2 ") );

// At this point, wrapper.childNodes.length === 2
// wrapper.childNodes[0].textContent === "Part 1 "
// wrapper.childNodes[1].textContent === "Part 2 "

wrapper.normalize();

// Now, wrapper.childNodes.length === 1
// wrapper.childNodes[0].textContent === "Part 1 Part 2 "
