Error updating jscript intellisense
You can still place definition files for use directly within your project manually.
I kept on getting these annoying JScript Intelli Sense errors every time I was editing a particular file.
This new information is provided by the Type Script language service, which uses static analysis behind the scenes to better understand your code.
Type Script uses several sources to build up this information: In Java Script, most of the time there is no explicit type information available.
For example, to give a partially declared object a specific type, you can use the See JSDoc support in Java Script for the Js Doc annotations currently supported.
Because Java Script and Type Script are now based on the same language service, they are able to interact in a richer way.
It's only when the stupid JScript intellisense tries to parse the file does it choke.
The next version of Visual Studio is going to be much more robust in this respect. We made some design decisions early on that we prevented us from making VS9 external references more robust. If that script is empty then it won't generate an error.
Note Starting in Visual Studio 2017, the Java Script language service uses a new engine for the language service (called "Salsa").
Details are included in this article, and you can also read this blog post.
// Note that assigning a value to "module.exports" is also supported.
Where type inference does not provide the desired type information (or to support documentation), type information may be provided explicitly via JSDoc annotations.
