To find an object in an array by one of its properties with JavaScript, we call the find method.
For instance, we write
const newData = [
{ investor: "Sue", stocks: 0, options: 0, savings: 0 },
{ investor: "Rob", stocks: 0, options: 0, savings: 0 },
{ investor: "Liz", stocks: 0, options: 0, savings: 0 },
];
const investor = "Rob";
const res = newData.find((x) => x.investor === investor);
to call newData.find with a callback that checks whether the investor property in the object being looped through equals to investor.
The first instance of the object where the condition is returned.
