ECMAScript 2015 or ES2015 is a significant update to the JavaScript programming language. It is the first major update to the language since ES5 which was standardized in 2009. Therefore, ES2015 is often called ES6.

To follow this ES6 tutorial, you should have a good knowledge of JavaScript up to ES5.

Section 1. New ES6 syntax

  • let – declare block-scoped variables using the let keyword.
  • let vs. var – understand the differences between let and var.
  • const – define constants using the const keyword.
  • Default function parameters – learn how to set the default value for parameters of a function.
  • Rest parameter – introduce you to the rest parameter and how to use them effectively.
  • Spread operator – learn how to use the spread operator effectively.
  • Object literal syntax extensions – provide a new way to define object literal.
  • for…of – learn how to use the for...of loop to iterate over elements of an iterable object.
  • Octal and binary literals –  provide support for binary literals and change the way to represent octal literals.
  • Template literals – learn how to substitute variables in a string.

Section 2. Destructuring

Section 3. ES6 Modules

  • ES6 modules – learn how to write modular JavaScript code.

Section 4. ES6 Classes

  • Class – introduce you to the ES6 class syntax and how to declare a class.
  • Getters and Setters – define the getters and setters for a class using the get and set keywords.
  • Class Expression – learn an alternative way to define a new class using a class expression.
  • Static methods – guide you on how to define methods associated with a class, not instances of that class.
  • Static Properties – show you how to define static properties shared by all instances of a class.
  • Computed property – explain the computed property and its practical application.
  • Inheritance – show you how to extend a class using the extends and super keywords.
  • new.target – introduce you to the new.target metaproperty.

Section 5. Arrow Functions

Section 6. Symbol

  • Symbol – introduce you to a new primitive type called symbol in ES6

Section 7. Iterators & Generators

  • Iterators – introduce you to the iteration and iterator protocols.
  • Generators – develop functions that can pause midway and then continue from where they paused.
  • yield – dive into how to use the yield keyword in generators.

Section 8. Promises

  • Promises – learn about Javascript Promises, what they are, and how to use them effectively.
  • Promise chaining – show you how to execute multiple asynchronous operations in sequence.
  • Promise composition: Promise.all() & Promise.race() – learn how to compose a new promise out of several promises.
  • Promise error handling – guide you on how to handle errors in promises.

Section 9. ES6 collections

  • Map – introduce you to the Map type that holds a collection of key-value pairs.
  • Set – learn how to use the Set type that holds a collection of unique values.

Section 10. Array extensions

Section 11. Object extensions

Section 12. String extensions

Section 13. Proxy & Reflection
