Hello, My learning track was updated for Javascript. The syntax ${} has now been incorporated- what does this mean?

Also instead of my function popping up w/ student (or even undefined when ='student' is taken out) for the exercises it keeps popping up w/ ${name} for function:

function sayHello(name = 'student') { return 'Good morning, (name)!'; }
