The consistency of Rust

Rust is consistent, and it helps to prevent future bugs.

Consider this example:

Running this will show incompatible error type which is interesting. Guess why?

Because the value of if condition is int type but in else is string type.

error[E0308]: `if` and `else` have incompatible types
 --> src/main.rs:6:9

3 |       let number = if condition {
  |  __________________-
4 | |         5
  | |         - expected because of this
5 | |     } else {
6 | |         "six"
  | |         ^^^^^ expected integer, found `&str`
7 | |     };
  | |_____- `if` and `else` have incompatible types

Change to this :

Will succeed.
