You can't have newlines in JSON strings. Instead use \n (or \r\n on windows). But VS code expects you to pass different lines as different strings. So, you can change your body to

[
     "const handle = () => {",
     "$0",
     "}"
]

$0 is where your cursor will be if you accept the hint. The pressing tab will take you to $1, $2, $3, ....
