      • DataView get/set Uint8Clamped methods S1

      Proposal details
      Proposal overview

      This proposal addresses the lack of DataView get/set methods for Uint8ClampedArray, which prevents consistent dynamic dispatch across all typed array types. It proposes adding the corresponding methods to complete Typed Array support.

      Note

      DataView get/set Uint8Clamped methods

      There are currently 11 kinds of Typed Array in the language.

      Stage: 1

      Motivation/Use Case

      I'd like to dynamically dispatch to DataView methods based on the "type" of the Typed Array. This works great for all of the types except Uint8Clamped.

      Problem

      Only 10 of them have DataView get/set methods.

      Here's a matrix representing the consistently available functionality for each of them:

      Float64Array :white_check_mark: :white_check_mark: :white_check_mark: :white_check_mark: :white_check_mark:

      Solution

      Add the get and set methods to round out Typed Array support.
