## String Interpolation: `"text @{expr}"` Interpolation works automatically inside string literals - no `format!()` needed: ```rust let name = "World"; let count = 42; let code = ts_template! { console.log("Hello @{name}!"); console.log("Count: @{count}, doubled: @{count * 2}"); }; ``` **Generates:** ```typescript console.log('Hello World!'); console.log('Count: 42, doubled: 84'); ``` This also works with method calls and complex expressions: ```rust let field = "username"; let code = ts_template! { throw new Error("Invalid @{field.to_uppercase()}"); }; ```
