elif

The elif keyword introduces an additional condition in an if chain. It is evaluated only when the preceding if/elif conditions were all falsy, providing a more compact form than nested else { if ... }.

Syntax & Example​

let temp = 22;
if temp < 0 {
    print("freezing");
} elif temp < 15 {
    print("cold");
} elif temp < 25 {
    print("comfortable");
} else {
    print("hot");
}

Use Cases​

  • Building multi-way decision ladders without deep nesting.
  • Expressing ordered ranges or priority-ordered conditions.
