How to make Visual Studio Code check entire project for errors? : <p>I'm using VS Code for TypeScript/JavaScript development.  When I open a file it will check that file for errors.  The problem is if I'm refactoring (like I move some shared code to a new location or change a name) it won't show me the errors this caused until I open the file with the problem.  ...so if I want to do extensive refactoring I have to open every file just to make it scan the file for errors.</p>

<p>How can I make VS Code scan the whole project for errors without having to open each file one by one manually?</p>
