## Pattern Matching: `{#if let}` 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} }; ```
