What is the most concise way to express this in the most recent version of JavaScript?

Here's what I have:

const id = speakerRec.id;
const firstName = speakerRec.firstName;
const lastName = speakerRec.lastName;

I believe there is a similar syntax to this, but it is slipping my mind.

const [id, firstName, lastName] = speakerRec;

Answer №1

Make sure to use {} when destructuring object properties:

const {name, age, occupation} = personDetails;

When it comes to array destructuring, remember to use []:

const [red, green, blue] = ["#FF0000", "#00FF00", "#0000FF"];

Check out this example for a better understanding:

const personDetails = {
  name: "Alice",
  age: 30,
  occupation: "Engineer"
};

const { name, age, occupation } = personDetails;

console.log(name);
console.log(age);
console.log(occupation);

const [red, green, blue] = ["#FF0000", "#00FF00", "#0000FF"];

console.log(red);
console.log(green);
console.log(blue);

Answer №2

This piece is referring to an item that should be treated as an object, therefore it suggests the usage of object destructuring instead of array destructuring:

By utilizing the syntax below, one can destructure the 'speakerRec' object into its individual properties:
const { id, firstName, lastName } = speakerRec;
