`if` statements follow C syntax:
```rust
if foo(x) {
print("It's true!");
} else if bar == baz {
print("It's true again!");
} else if ... {
:
} else if ... {
:
} else if baz.is_foo() {
print("Yet again true.");
} else if foo(bar - baz) {
print("True again... this is getting boring.");
} else {
print("It's finally false!");
}
```
All branches of an `if` statement must be enclosed within braces '`{`' .. '`}`', even when there is only one statement.
Like Rust, there is no ambiguity regarding which `if` clause a statement belongs to.
Unlike C, the condition expression does _not_ need to be enclosed in parentheses '`(`' .. '`)`', but
all branches of the `if` statement must be enclosed within braces '`{`' .. '`}`',
even when there is only one statement inside the branch.
Like Rust, there is no ambiguity regarding which `if` clause a branch belongs to.
```rust
// Rhai is not C!
if (decision) print("I've decided!");
// ^ syntax error, expecting '{' in statement block
```
