Definition and Usage
The children property returns a collection of an element's child elements, as an HTMLCollection object.
The elements in the collection are sorted as they appear in the source code and can be accessed by index numbers. The index starts at 0.
Tip: You can use the length property of the HTMLCollection object to determine the number of child elements, then you can loop through all children and extract the info you want.
The difference between this property and childNodes, is that childNodes contain all nodes, including text nodes and comment nodes, while children only contain element nodes.
Browser Support
The numbers in the table specify the first browser version that fully supports the property.
