Mechanism to provide number grouping in numeric literals

When I want to write code to put timeout for 3 seconds, I prefer to write.

setTimeout(afunction, 3 * 1000);

This to avoid accidentally putting 30000 (or 300).
I wish there was mechanism to provide number grouping in numeric literals.

Java and C# come up with a underscore format.

Additional Numeric Literal Formats)

Is there an plan/proposal for number grouping in JavaScript?
