this-types for functions (#6739) Defines ability to define type of this for the scope of a function. If you're in a class, this is assumed to have the type of the class itself. You can still override this by giving an explicit type to this. Strict this checks Problem: cognitive burden by creating a distinction between types of methods and properties with function types. Looked at performance again
6702 - readonly in .d.ts files Problem: typescript@next users can't give their generated .d.ts files to 1.8 users What's the difference between this and e.g. union types? This one doesn't require any opting-in Not universally true -- some expressions became union types, for example Options Commandline flag Tool (regexp or something smarter) Don't emit readonly in .d.ts until 2.0 ships, or "later"
This is a prototype for numeric literal types, in the same vein as string literal types. All numeric syntaxes supported by JS should be supported (as far as I know) in type positions. Additionally, NaN and Infinity are builtin to the typespace as literal subclasses of number. Also with this change: The unary - operator gets contextually typed if its parent is contextually typed and it applies nega
To ensure tree transformations in the TypeScript compiler are efficient, we compute information about various required transformations for each node. Transform flags are aggregated in a bottom-up fashion, so that we already have information about a node's subtree when we compute the transform flags for the node. These transform flags are initially computed during the bind phase of the compiler, as
