deep-child-element-count

Like ParentNode.childElementCount but counting all the nested children too.

Example:

const deepChildElementCount = require('deep-child-element-count')
 
var container = document.createElement('div')
 
var firstChild = document.createElement('div')
container.appendChild(firstChild)
 
var secondChild = document.createElement('div')
var containedChild = document.createElement('div')
secondChild.appendChild(containedChild)
container.appendChild(secondChild)
 
console.log(container.childElementCount)
// => 2
 
console.log(deepChildElementCount(container))
// => 3
