Search Terms: parseDiagnostics

Currently there's no API to directly get the parseDiagnostics of a SourceFile.
The only possible solution is creating a Program with this SourceFile and call program.getSyntacticDiagnostics(sourceFile)...

This is especially painful when using ts.parseJsonText or ts.readJsonConfigFile where I need to check for parseDiagnostics.

Is there a reason this property is internal? Given that it's always set, I think it's safe to expose it.

Related question: why is getJavaScriptSyntacticDiagnosticsForFile declared in program.ts and not directly exposed directly? This function doesn't rely on Program, TypeChecker, Resolver, or Binder.
If I want all syntax errors of a JavaScript file, I need to create a Program first.

You could resolve both issues by just exposing getSyntacticDiagnostics as a function from program.ts (or moving it to a different file).
