A Proposal For Type Syntax in JavaScript - TypeScript
Today we’re excited to announce our support and collaboration on a new Stage 0 proposal to bring optional and erasable type syntax to JavaScript. Because this new syntax wouldn’t change how surrounding code runs, it would effectively act as comments. We think this has the potential to make TypeScript easier and faster to use for development at every scale. We’d like to talk about why we’re pursuin

GitHub - tc39/proposal-is-usv-string: a proposal for a method to determine if a String is welll-formed Unicode
ECMAScript string values are a finite ordered sequence of zero or more 16-bit unsigned integer values. However, ECMAScript does not place any restrictions or requirements on the integer values except that they must be 16-bit unsigned integers. In well-formed strings, each integer value in the sequence represents a single 16-bit code unit of UTF-16-encoded Unicode text. However, not all sequences o
