Does "let" stand in place for constant then?

for example:

let language = "Swift"

Hey Alejandro Chanocua,

Yes, "let" is the keyword to define a constant in Swift. It specifies that this value is immutable. You can also define variables with the "var" keyword. The var keyword specifies that the value is mutable or is allowed to change.

Good Luck

I get an error because earlier in the code i declared language to be a variable.
