Summary: In this video, we will discuss more ECMAScript 6 features. We already know that ECMAScript 6 is not supported in all browsers. This is why we will do all of our testing in Chrome Canary. Today, we will talk about two important features: let and const. let will help you declare a variable in the inner block with the same name as the variable in the outer block. const, as you know it from other languages like C# and Java helps you declare variables with values that do not change throughout the execution of the program.
