WebAssembly.Tag.prototype.type()

The type() method of the Tag object can be used to get the sequence of data types associated with the tag.

Syntax

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 retrieves them using type():

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

The object logged to the console will look like so:

json

{
  "parameters": ["i32", "i64"]
}
