Destructuring

Destructuring pulls typed values out of arrays and objects into named variables.

destructuring.ts

const user: [string, number] = ;
const [name, lessonCount] = user;

const nextLesson: string = "objects";
const message: string = `${name} has ${lessonCount} lessons before ${nextLesson}.`;

console.log(message);

const user: [string, number] = ;
const [name, lessonCount] = user;

const nextLesson: string = "objects";
const message: string = `${name} has ${lessonCount} lessons before ${nextLesson}.`;

console.log(message);

const user: [string, number] = ;
const [name, lessonCount] = user;

const nextLesson: string = "objects";
const message: string = `${name} has ${lessonCount} lessons before ${nextLesson}.`;

console.log(message);
