I have the following string in bash
"3.8,3.9,3.10"
Is there a way using shell to convert it into a json array, i.e.
["3.8", "3.9", "3.10"]

Since the string (including its double quotes) seems to be a properly formatted JSON string, we could pass it, as JSON, to the JSON processor jq and split it on the commas:
$ echo '"3.8,3.9,3.10"' | jq 'split(",")'
[
"3.8",
"3.9",
"3.10"
]
Use jq with -c to get "compact output":
$ echo '"3.8,3.9,3.10"' | jq -c 'split(",")'
["3.8","3.9","3.10"]
Giving it to an internal jq variable on the command line and then splitting that variable's value:
$ jq -c -n --argjson str '"3.8,3.9,3.10"' '$str|split(",")'
["3.8","3.9","3.10"]
