VS Code snippet: How do I make a camelCase variable transformation based on a CamelCase variable?

Goal: In VS Code, I'm trying to create a snippet that takes "FooBar" and outputs "FooBar fooBar".

Current Code: I have "$1 ${1:camelcase}" for the body of my snippet. But it outputs "FooBar FooBar." I have tried a number of other options but none seem to work. I know it's probably something relatively simple that I'm missing.

Question: What is the correct syntax to make only the first letter of my variable name become lowercase?

All you really need is the first letter and ignore the rest:

  "$1 ${1/(.)/${1:/downcase}/}",

or using the newer camelcase option:

  "$1 ${1/(.*)/${1:/camelcase}/}",

you just split the string in two parts

${1/(.)(.*)/${1:/downcase}${2}/}
