How to return a character n times before an element react

Tags: , , , ,



I want to add a random amount of characters before an element, repeat that element 20 times, with a diffrent amount of characters before each time. For example:

function App() {
  return (
    <>
      Hello World! This is time {i}
      // I want to add a random amount of spaces before the h1 tags above. I also want to repeat that h1 tags 20 times with a different amount of spaces before each h1 tag
    </>
  )
}

An example of what I want to return is

  Hello World! This is time 1
   Hello World! This is time 2
         Hello World! This is time 3
     Hello World! This is time 4
………
Each with a diffrent amount of spaces.

Answer

function HeaderWithLeadingSpacing({ maxSpacing = 20, num }) {
  const rdn = Math.round(Math.random() * maxSpacing);
  const spacing = Array.from(Array(rdn), () => 'u00A0');
  
  return (
    <h1>{spacing}Hello World! This is number {num}</h1>
  )
}

function App() {
  return Array.from(Array(20), (_, i) => (
    <HeaderWithLeadingSpacing
      maxSpacing={10}
      num={i + 1}
    />
  ));
}

ReactDOM.render(<App />, document.getElementById('app'))
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.6.3/umd/react.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.6.3/umd/react-dom.production.min.js"></script>



<div id="app"></div>

If I have understood correctly, the above code should do the trick.
