Equivalent in React of *ngFor in Angular 2

Question

You can use map on numbers and create the options dynamically like this:

<select>
    {
       numbers.map(el => <option value={el} key={el}> {el} </option>)
    }
</select>

Check this example:

var numbers = [...Array(100).keys()];

var App = () => {
   return(
      <select>
        {
           numbers.map(el => <option value={el} key={el}> {el} </option>)
        }
      </select>
   )
}

ReactDOM.render(<App/>, document.getElementById('app'))

<div id='app'/>
