Is there any LLVM backend for javascript? If not, other tools that convert dynamic language(similar to javascript) to LLVM IR will also be okay. Because I am writing a dynamic language compiler and such tools can help me find out how some features are implemented.

@AndersonGreen It is just a toy language created by myself, similar to javascript. – AllenLin Dec 17 '15 at 13:34

there are few projects on github about it. One of them is TypeScript Native Compiler (https://github.com/ASDAlexander77/TypeScriptCompiler) – Alexander77 Sep 29 '21 at 18:25

FTL JIT (JavaScriptCore) uses LLVM as a backend.

4As of Feb 2016, FTL JIT (Webkit) no longer uses LLVM; they use B3 (Bare Bones Backend) JIT: https://webkit.org/blog/5852/introducing-the-b3-jit-compiler/ – dubek Oct 15 '17 at 12:49
