For me autocomplete works out of the box in all projects. There is also a bulb next to the file type in the bottom right corner which suggests to create a jsconfig file for you for better intellisense support. I haven't noticed any difference after creating it though. VSCode makes JS suffer able for me :P
Which language are you trying to autocomplete. For some like Javascript/Typescript, it works out of the box. For many like Golang, C++, Python you need to install a plugin but takes just a few seconds. Also for autocomplete to work across files, I think you many need to open the whole directory ("file/open folder..." menu item.)
