ECMAScript 6 or ES6 is the version 6 for the JavaScript programming language which comes after the version 5. ES6 was introduced around 2015 and was later named to ECMAScript 2015. ES6 comes with a lot of handy and advanced features that helped JavaScript dominate the Web Development and in general, the Software industry today.
Due to ES6, we can now use JavaScript to make large scale web applications and other types of software today.
In our entire JavaScript tutorial, time after time, we will frequently use and explain much of the features ES6 gave us.
Some of the most used ES6 features are listed below:
