WebAssembly.Tag.prototype.type()

None

An object with a property named parameters that references the array of data types associated with this Tag.

This is a copy of the type object that was originally passed into the Tag() constructor.

This code snippet creates a tag defining two data types and then exports them using type(). The result is printed to the console:

const tag = new WebAssembly.Tag({ parameters: ["i32", "i64"] });
console.log(tag.type());

// Console output:
// Object { parameters: (2) […] }
//   parameters: Array [ "i32", "i64" ]
//   <prototype>: Object { … }
