DISCLAIMER: this tool has been modified for didactic purposes. The original tool is available at here. The main modifications are additional keywords added to the core language. Type checking has also been disabled to simplify implementing their behaviors.
WebAssembly has a text format (.wat) and a binary format (.wasm) . This tool converts from the text format to the binary format.
Enter WebAssembly text in the textarea on the left. The right side will either show an error, or will show a log with a description of the generated binary file.
