Convert string to object array

I want to convert string to object array. Suppose I have following string.

const str = "someValue,display";

I want to convert it like following.

[{
  columnVal: "someValue",
  display: true
}]

if it’s display then I want value as true if noDisplay then false.

I tried following but, doesn’t seems like best solution.

const val = "someValue,display";
const obj = {};

val.split(",").forEach((str, index) => {
    if(index === 0) {
        obj.columnVal = str;
  } else {
    if(str == "display") {
        obj.display = true;
    } else {
        obj.display = false;
    }
  }
})
console.log([obj]);

Using a loop when you want to do something with specific indexes seems wrong. Just access the elements you want and set the appropriate object properties.

const val = "someValue,display";
const vals = val.split(",");
const obj = {
  columnVal: vals[0],
  display: vals[1] == "display"
};

console.log([obj]);
