Tests:

Recursive rendering
const userData = [{name: 'a', age: '2'},{name: 'a', age: '2', child: [{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'}]},{name: 'a', age: '2'},{name: 'a', age: '2', child: [{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'}]}] ReactDOM.render(React.createElement(RenderRecursively, {userData: userData}), document.getElementById('root'))
Non recursive rendering
const userData = [{name: 'a', age: '2'},{name: 'a', age: '2', child: [{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'}]},{name: 'a', age: '2'},{name: 'a', age: '2', child: [{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'},{name: 'a', age: '2'}]}] ReactDOM.render(React.createElement(RenderNonRecursively, {userData: userData}), document.getElementById('root'))
