getModeForUsageLocation
abstract fun getModeForUsageLocation(file: SourceFile, usage: StringLiteralLike): ResolutionMode(source)
Calculates the final resolution mode for a given module reference node. This is the resolution mode explicitly provided via import attributes, if present, or the syntax the usage would have if emitted to JavaScript. In --module node16 or nodenext, this may depend on the file's impliedNodeFormat. In --module preserve, it depends only on the input syntax of the reference. In other module modes, when overriding import attributes are not provided, this function returns undefined, as the result would have no impact on module resolution, emit, or type checking.
