React ES6

React development relies heavily on ES6 (ECMAScript 2015) features. Familiarity with these concepts is crucial.

Classes

Classes are a template for creating objects. They encapsulate data with code to work on that data.

Arrow Functions

Arrow functions allow for a short syntax for writing function expressions.

Variables (let, const, var)

Before ES6, var was the only way to declare variables. ES6 introduced let and const.

Array Methods (.map())

The .map() method is frequently used in React to render lists of items.

Destructuring

Destructuring makes it easy to extract array elements or object properties into distinct variables.

class Car {
  constructor(name) {
    this.brand = name;
  }
}

const mycar = new Car("Ford");
console.log(mycar.brand);
