How to set tooltips in vscode?

Question

Visual Studio Code

DD, maybe I didn’t express myself correctly in the question, tell me how to set up hints / substitutions (I don’t know how to express it exactly, an example from webstorm (WS) , i.e. it substitutes data from a file, also if you access global vue objects in this case, to storages, routes, it always suggests variables, methods that are already there, as well as built-in vue methods, is it possible to set up something similar in vscode, because it’s very difficult for me to develop, and WS shows the response speed as if it was launched on tamogochi, I would like to use an editor from microsoft, but it very rarely substitutes standard methods for data for me, it also does not substitute variables that are declared so often, but it constantly throws out such useful information in a huge amount
Tell me with the setting, maybe someone has a good config for js or advice.
