Inlay Hints

Inlay hints appear in the editor and provide you with additional information about your code to make it easier to read.

  • Parameter hints appear next to a parameter in a function call show you the name of the parameter from the function definition.

  • Return type hints are by default shown for chained methods that are split between multiple lines and return at least 2 different types. The type information is inferred from a JSDoc comment or based on the static analysis of your code.
