Intellisense inside JS template literal not showing automatically after typing ${

[zzJinux]

• VSCode Version: 1.15.1
• OS Version: Windows 10 Pro 1703

Steps to Reproduce:

While typing inside the string interpolation, e.g.${foo}, Intellisense popup for the variable is not shown.

Intellisense regarding the variable's property works perfectly though.
But, It's the variable name that popup doesn't open when typing.

Reproduces without extensions: Yes

I think we just don't automatically trigger intellisense in this case. If you use the editor.action.triggerSuggest keybinding (ctrl+space on mac) after the { do you see the proper intellisense?

[zzJinux]

Yes, I see.
You mean that's intended operation?

Glad the workaround works.

This is a bug though. I'm going to change the title of this issue to make the root cause of problem more clear

After thinking over this further, I don't believe we should automatically show suggestions when you type ${. Instead my proposal is that we show suggestions once you start typing the next character, such as ${a. This is how quick suggestions work normally in JS.

The reason for this is that the template substitution may contain any expression, and automatically showing suggestions on ${ will make it more annoying to enter expressions such as ${123} or ${[a]}.

Closing this as a duplicate of #34857, which tracks showing quick suggestions on cases such as ${a
