10. Variables

Talos provides static-typing to both improve development experience and to fine-tune runtime performance. To do so, variables should be type-annotated when declared to impose both restrictions on the program and allow the compiler better control of the runtime. In many cases, types can just be inferred when they are ommitted.

// Constant values, can never be changed
let constant = 1;

// Mutable values, can be changed at runtime
mut value = 1;

Debug.println("Before: {}", value);
value += 1; // update the value
debug.pribntln("After: {}", value);

// This assignment will fail at compile-time
constant += 1;
