Mapping through an array

John Jones

Inside the arrow function, index is 0 and element is "foo". The value of element is "foo".

Library: react

{names.map((element,index)=>{ console.log(‘inside arrow function’) console.log(‘index is ‘+index+‘ element value is :’+element)})

or

<ul>
  {todos.map(todo=>(
    <li>{todo}</li>
  ))}
