Excellent video, thank you so much... by the way, to store Sarah in name, just type name = 'Sarah' after the name variable declaration

I loved your explanations and your teaching ways. it helps me a lot. for answering your question.
since you mention at your course that let data type cannot be redeclared in the same block, so i guess to redeclared the values, just declare out of the block, so it would be like:
function greet(){ let name = 'jane'; console.log('Greeting you ' + name); }//this is the 2nd block
let name = 'Sarah'; console.log('Greeting you ' + name);

When would it be better to use "let" than "var" ?
