What parameters can React.createElement() take in?

For instance, this code snippet:

React.createElement(
  "h1",
  null,
  "Shopping List for ",
  props.name
),

What does the null value represent, or what can it be used for?

From the React docs:

createElement()

React.createElement(
  type,
  [props],
  [...children]
)

Create and return a new React element of the given type. The type argument can be either a tag name string (such as 'div' or 'span'), a React component type (a class or a function), or a React fragment type.

What the docs don’t explicitly mention is that props should be an object. For example:

{
  click: dothing,
  className: 'myClass'
}

It may be {} or null if you need to specify children but not properties
