1. Improved JSDoc comments for better type check in VSCode with “implicitProjectConfig.checkJs": true” to enable type checking for JavaScript.
2. Introduced JSDoc type casting to solve problems with type coercion.
3. Escaped expando properties like “splitText” with [''] to resolve warning that property does not exist on object.
4. Updated JSDoc comment for VNode. Attribures property was set to type “object”. Unfortunately JSDoc types “object” and “Object” get treated as type “any” by TypeScript. To indicate a generic object you have to use this signature: Object.<string, any>.
5. Add type cast for Ctor being called with new keyword to avoid warning "Cannot use 'new' with an expression whose type lacks a call or construct signature".
6. Added type casting where type is a function, but original value could be a string as well. This tells type checker that the value can be called.
7. Added numerous type casts in diff.js to resolve type conflicts.
8. Many types had to be cast to type “any” in oder to remedy conflicts where type coercion would happen during runtime in browser, but static type checkers can’t foresee.
9. Type casting adds an extra pair of parens around the value being cast. But these are removed during minification.

1. A text Node is also of type Node. So we can cast to that instead of type 'any'.

jsdoc updates rebased on upstream master

1. Cannot use union inside brackets. This was showing children as type `string | VNode[]` when it should have been `string[] | VNode[]`.
