I'm not sure there's a particular difference between the two except the keyword chosen. You type "auto my_var_name = func_call()" or you type "let my_var_name = func_call()". In both cases you get an inferred type for a variable. Mutability is very different in C++ though - const is quite a complex topic, and isn't as simple as "this variable binding is/isn't mutable".
