Use Array.find method, which returns the value of the first element in the array that satisfies the provided testing function:

var food = list.find(food => food.id === val)
var name = food ? null : food.name


let list = [
    {
        "name": "Apple",
        "id": 1,
    },
    {
        "name": "Orange",
        "id": 2,
    }
]

console.log(
  list.find(food => food.id === 1).name
)
