How can you extract a JSON object from a JSON array based on a key that is associated with a specific JSON

Is it possible to retrieve a specific JSON object from an array of JSON objects based on a condition?

[
{ id: 1, name: "larry" },    
{ id: 2, name: "curly" },
{ id: 3, name: "moe" }
]

For example, if I want to extract the object where name is equal to "larry", can this be done?

{ id: 1, name: "larry" }

It seems like I understand your question, but would this code be what you're looking for?

let myData = jsonObj[0];

console.log(myData.id + " " + myData.name);

Alternatively, if you want to search by name:

let myData;

for (let j = 0; j < jsonObj.length; j++){
  // find the object with a matching name
  if (obj[j].name === "larry"){
     // match found
     myData = obj[j];
  }
}
