To use Array.includes() to find object in array with JavaScript, we use the some method.
For instance, we write
const arr = [{ a: "b" }];
console.log(arr.some((item) => item.a === "b"));
to call arr.some with a callback that checks if item in arr has property a equal to 'b'.
If any object in arr has property a equal to 'b' then it returns true.
