Courses Plus Student 11,897 PointsUsing const and var in coursework
In the previous code challenge, the variables are declared with the var keyword. Changing to a construction with the const syntax also works, but both are accepted as correct. The coursework at this point (and in the workshop on variable declaration) suggests that var is deprecated and should be avoided. So--a little confused about how to proceed.

const keyword: when you do not want the value of your variable to change let keyword:when you want the value to change
For example, you could select a button with the const keyword and target a list item in a list with the let keywod.
Happy Coding!

Courses Plus Student 11,897 PointsSure, I understand the difference. I guess my concern was about the inconsistency in the courseware. Sounds like the vars are artifacts of stages that haven't been updated, not "gotcha" questions meant to help us more to the ES2015 standard.
