array.map() is returning elements all together in React JS

Question

const test = () = {

const array = ['hello', 'myNameIs']

return (

{
array.map((arr) => (
  <div>{arr}</div>
  <button>Edit</button>
  )
}

)

}

This.map() method is not working as I intended.

With the code, I was trying to get

hello [button]
myNameIs [button]

like this.

But when I actually render the code, I get

hello MynameIs [button]

In this kind of situation, How can I change the.map() statement?

Should I use an index?

Answer 1

Take a look at below example, I created it almost by your code, it is working as you expected without problem.

 function App() { const array = ['hello', 'myNameIs']; return array.map(item => ( <div key={item}> {item} <button>Edit</button> </div> )); } ReactDOM.render(<App />, document.getElementById("root"));

Answer 2

Create the button inside the div tag

array.map((arr) => (
  <div>{arr} <button>Edit</button></div>
 )

Answer 3

const test = () = {
  const array = ['hello', 'myNameIs']
  return (

  {array.map((item,key) => (
    <div key={item}>{item}</div><button>Edit</button>
  )})
}

Answer 4

You are not using the correct syntax for the arrow function It should be like const test = ()=>{} React component JSX should return one parent container try wrapping it like:

 const Test = () => { const array = ["hello", "myNameIs"]; return ( <> {array.map((arr) => { return ( <> <div>{arr}</div> <button>Edit</button> </> ); })} </> ) }
