React map() - like we do with handlebars

Hi I can’t do with this like we use to do with handlebars - to do something {{for each}} how can we achieve that with react, I am trying to do post list for blog to make it simple I did something like this:

let a = {

  news:[
    {
      name: 'Name 1',
      age: 33,
    },

    {
      name: 'Name 2',
      age: 36,
    },

    {
      name: 'Name 3',
      age:  6,
    },

    {
      name: 'Name 4',
      age: 3,
    },
  ]

}

let arrayOfJsx = a.map( item =>

I am { this.news.name}
I am { this.news.age} years old.
)

class NewsList extends React.Component {

  render() {

      return(
        <div id="news-list" className="news-posts-list" >
        { arrayOfJsx }
          </div>

      )
  }

}
