Difference between Wast and Wat

[xtuc]

You mentioned the suggar of the WebAssembly text format, but it's missing a bit of formal definition.

WebAssembly specifies a textual representation called wat (WebAssembly Text Format): https://webassembly.github.io/spec/core/text/index.html, which is a direct mapping from the binary version. It has no nesting nor identifiers (everything is index based).

The suggared version is called wast (WebAssembly "Script Text Format): https://github.com/WebAssembly/spec/tree/master/interpreter#s-expression-syntax, it's not part of the official specification and is made for convenience (used in the spec tests).

@xtuc, thanks for your comment.

I intended "folded instructions" as the sugared version.

I will understand the difference between the two from now.

Thank you for teaching me.
