## Pattern Matching: `&#123;#if let&#125;` Use `if let` for pattern matching on `Option`, `Result`, or other Rust enums: ```rust let maybe_name: Option<&str> = Some("Alice"); let code = ts_template! { {#if let Some(name) = maybe_name} console.log("Hello, @{name}!"); {:else} console.log("Hello, anonymous!"); {/if} }; ``` **Generates:** ```typescript console.log("Hello, Alice!"); ``` This is useful when working with optional values from your IR: ```rust let code = ts_template! { {#if let Some(default_val) = field.default_value} this.@{field.name} = @{default_val}; {:else} this.@{field.name} = undefined; {/if} }; ```
