How to find out the type of a TypeScript element (variable, function) in WebStorm?

Question

Is there a way in WebStorm to get the type of a function or a variable?

In Visual Studio Code, I can hover over an identifier, and I get type information about the element under the cursor:

It can also show the effective type of a variable:

Both are extremely helpful tools for better understanding the code.

Is there a way in WebStorm to access the effective type of an element in the editor?

Answer 1

• Ctrl+Shift+I (View/Quick Definition)

• Try Ctrl+Shift+P (View/Expression Type) - it normally shows the inferred variable type

Since WS2017.2 Ctrl+Hover shows inferred type.
