Introduction to ES6+

Introduction to ES6+

Welcome to ES6+, the latest version of JavaScript that brings a slew of new features and enhancements to the language.

What's New in ES6?

ES6+ includes exciting new features like arrow functions, template literals, destructuring assignment, classes, enhanced object literals, rest and spread operators, modules, sets and weak sets, maps and weak maps, promises, async/await, generators, and more.

Arrow Functions

Arrow functions (() => {}) provide a concise syntax for writing functions, making code more readable and maintainable.

Template Literals

Template literals (``) allow for easy string interpolation and multi-line strings, simplifying string manipulation.

Destructuring Assignment

Destructuring assignment makes it convenient to extract properties from objects and arrays into variables.


Classes provide a structured and object-oriented way to define and create objects in JavaScript.

Enhanced Object Literals

Enhanced object literals add new features such as property shorthand, computed property names, and method definitions within objects.

Rest and Spread Operators

Rest (...) and spread (...) operators simplify working with variable numbers of arguments and combining arrays or objects.


Modules provide a mechanism for code organization and reuse, allowing for modular development and encapsulation.

Sets and WeakSets

Sets and weak sets are collection types that store unique values. Sets maintain insertion order, while weak sets allow values to be garbage collected.

Maps and WeakMaps

Maps and weak maps are key-value collections. Maps allow any value as keys, while weak maps allow values to be garbage collected.


Promises represent the eventual completion (or failure) of an asynchronous operation, providing a way to handle asynchronous code efficiently.


Async/await provides a cleaner and more synchronous-like syntax for working with asynchronous code, making it easier to handle promises.


Generators are functions that can pause and resume execution, yielding values one at a time, making them useful for creating iterators and implementing custom control flow.

New ES6 Methods for Built-in Objects

ES6 introduces numerous new methods for built-in objects like arrays, strings, and numbers, providing enhanced functionality for common operations.

In the next session, we'll explore the importance and usage of let and const, the new variable declarations introduced in ES6. Stay tuned!
