how can I put a logic in map array method. I have sent title as props and except props title I want to render other title

Here, when I click bitcoin. Parent component sends bitcoin as title. I don’t want to include bitcoin in the select tag.

>Solution :

You are returning the option directly from your map function, if you want to add logic inside just add {} and a return statement inside

{coins.map((item) => {
    // you can put your logic here
    // for example just first 2 letters
    const customTitle = item.title.slice(0, 2)
    return (
        <option>{customTitle}</option>
    )
})}
