Haha.. @Ipang, I made the same mistake too, always thought that let and var belong to JavaScript. I deleted my answer now.. 😜

It clearly shows the difference. let indicates constant variable, which is not to be changed. var is just regural variable.

let creates a constant. Once the value is set to a let identifier it cannot be changed unlike a var.
