react conditional return component code example

Example 1: how to use if else inside jsx in react

renderElement(){
   if(this.state.value == 'news')
      return data;
   return null;
}

render() {
    return (   
        
            { this.renderElement() }
        
    )
}

Example 2: react native conditional rendering

class Component extends React.Component {
	const a = true
	render() {
      return (
    	
          {a == true
           ? ()
           : null
          }
            	
	  )
	}
}

This is staying: if a == true, render a button component. 
Otherwise render null, in other words nothing.
