Examples

// block { const a = 1 // block-scoped constant let b = 2 // block-scoped variable }

// template literals function complexToString(a, b) { return `${a} + ${b}i` } complexToString(1, 2)

// multi-line strings let html = &#96; <div> Hello </div>&#96;

// destructing assignment const [a, , c] = [1, 2, 3, 4] const {a, c} = {a: 1, b: 2, c: 3, d: 4}

// class class Person { constructor(name) { this.name = name }

hello() { return ‘Hello, ‘ + this.name + ‘!’ } }

const erik = new Person(‘Erik’) erik.name erik.hello()

// inheritance class Student extends Person { hello() { return ‘Hello, student ‘ + this.name + ‘!’ } }

const patrik = new Student(‘Patrik’) patrik.hello()

// arrow functions [1, 2, 3].map(value =&gt; value + 1)

const increment = value =&gt; value + 1 increment(1)

// for of let sum = 0 for (const element of [1, 2, 3]) sum += element

// default parameters function hello(name = ‘Erik’) { return ‘Hello, ‘ + name + ‘!’ }

// rest parameters function restParams(first, …rest) { return rest }

// spread operator Math.max(1, 2, 3) Math.max(…[1, 2, 3])

const a = [1, 2, 3] const b = [4, 5, 6] const c = […a, …b]
