How to enable auto-suggestions in Sublime Text?

Question

Sublime Text

Here I am running a project, I have a dozen folders and files, there are variables and function names, can Sublime tell me the names of variables (function names) that I use throughout the project in different files, well, that is, I declared a function in file X a when I write in file Y , it tells me its name. In general, how to do this, can you create a project somehow or something else?

Answer 1

File -> Open Folder...
И все работает. А если комментарии JSDoc писать, то еще и аргументы функции с описанием будет показывать.
