In this lesson from the Introduction to ES6 Challenges on freeCodeCamp we look further into the use cases and functionality of the "'let"' keyword. In ES6 the var keyword is less used in preference of some new keywords, in the case of this lesson, one of those keywords is "let"'. When using the "let" keyword we are able to limit its use to the block, expression, or statement in which we referenced it.
