New take on #29716 ## Summary Template literals consisting entirely of constant values will be inlined to a string literal, effectively replacing the backticks with a double quote. This is done primarily to make the resulting instruction a string literal, so it can be processed further in constant propatation. So this is now correctly simplified to `true`: ```js `` === "" // now true `a${1}` === "a1" // now true ``` If a template string literal can only partially be comptime-evaluated, it is not that useful for dead code elimination or further constant folding steps and thus, is left as-is in that case. Same is true if the literal contains an array, object, symbol or function. ## How did you test this change? See added tests. |

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
